Improvement or stabilization of the condition has been reported with topical and intralesional corticosteroids, antibiotics, hydroxychloroquine, topical and oral immunomodulators, tacrolimus, and most recently, 5-alpha-reductase inhibitors. In one study, the use of anti-androgens (finasteride or dutasteride) was associated with improvement in 47% and stabilization in 53% of patients

CCCA tends to present itself in the 20s and progresses over 20–30 years. One should consider this diagnosis in African Americans with what appears to be a female-pattern hair loss.

There is no standard treatment for alopecia universalis. Many treatments have been explored, including immunomodulatory agents such as imiquimod. Tofacitinib citrate may also have benefits. In June 2014, it was reported that a 25 year old man with almost no hair on his body grew a full head of hair, and eyebrows, eyelashes, facial, armpit and other hair, following 8 months of treatment.

Treatments for CCCA remain investigational. Altering hair care practices has not been proven to assist in hair rejuvenation. High-dose topical steroids, antibiotics, immunomodulators such as tacrolimus (Protopic) and pimecrolimus (Elidel), and anti-androgen/5alpha Reductase inhibitors have been used with unknown efficacy.

Dietary supplements are not typically recommended. There is only one small trial of saw palmetto which shows tentative benefit in those with mild to moderate androgenetic alopecia. There is no evidence for biotin. Evidence for most other produces is also insufficient. There was no good evidence for gingko, aloe vera, ginseng, bergamot, or hibiscus as of 2011. While lacking both evidence and expert recommendation, there is a large market for hair growth supplements, especially for products that contain biotin.

Many medications are being studied, including abatacept, MEXIS/M6S, triamcinolone, secukinumab, tralonkinumab, apremilast, botulinum toxin, INCB018424, bimatoprost, clobetasol, AS101, autologous platelet-rich plasma, topical minoxidil, and nitric oxide gel. Some of these medications are approved for other diseases, others are not available outside of studies.

In 2014, preliminary findings showing that oral ruxolitinib, a drug approved by the US Food and Drug Administration (FDA) for bone marrow disorder myelofibrosis, restored hair growth in three individuals with long-standing and severe disease. The medicine costs almost USD $10,000 a month.

2008 and 2012 reviews found little evidence to support the use of special lights or lasers to treat hair loss. Additionally none are approved by the FDA in America for this use. Both laser and lights appear to be safe.

A 2014 and 2016 review found tentative evidence of benefit for lasers. While another 2014 review concluded that the results are mixed, have a high risk of bias, and that its effectiveness is unclear.

As mentioned above, primary cicatricial alopecias are classified by the predominant type of inflammatory cells that attack the hair follicles: i.e., lymphocytes, neutrophils, or mixed inflammatory cells. Treatment strategies are different for each subtype and detailed treatment options are beyond the scope of this discussion. However, certain general principals are reviewed below.

Treatment of the lymphocytic group of cicatricial alopecias (including lichen planopilaris, frontal fibrosing alopecia, central centrifugal alopecia, and pseudopelade (Brocq) involves use of anti-inflammatory medications. The goal of treatment is to decrease or eliminate the lymphocytic inflammatory cells that are attacking and destroying the hair follicle. Oral medications may include hydroxychloroquine, doxycycline, mycophenolate mofetil, cyclosporine, or corticosteroids. Topical medications may include corticosteroids, tacrolimus, pimecrolimus, or Derma-Smoothe/FS scalp oil. Triamcinolone acetonide, a corticosteroid, may be injected into inflamed, symptomatic areas of the scalp.

Treatment of the neutrophilic group of cicatricial alopecias (folliculitis decalvans, tufted folliculitis) is directed at eliminating the predominant pathogenic microbes that are invariably involved in the inflammatory process. Oral antibiotics are the mainstay of therapy, and topical antibiotics may be used to supplement the oral antibiotics. In dissecting cellulitis, pathogenic microbes are not usually present. Isotretinoin in small doses may be helpful in treating dissecting cellulitis.

Treatment of the mixed group of cicatricial alopecias (folliculitis keloidalis) may include antimicrobials, isotretinoin, and anti-inflammatory medications.

You should discuss any treatment with your dermatologist, who will also explain potential side effects, as well as laboratory tests that are needed before starting treatment and sometimes are monitored during treatment.

The course of cicatricial alopecia is usually prolonged. Treatment is continued until the symptoms and signs of scalp inflammation are controlled, and progression of the condition has been slowed. In other words, itching, pain, tenderness, and burning have cleared, scalp redness, scaling, and/or pustules are no longer present, and the progression of the hair loss has been stopped or slowed. Treatment may then be stopped. Unfortunately, the cicatricial alopecias may reactivate after a quiet period and treatment may have to be repeated.

Surgical treatment for cosmetic benefit is an option in some cases after the disease has been inactive for one to two or more years. Hair restoration surgery or scalp reduction may be considered in these instances.

Dietary supplements are not typically recommended. There is only one small trial of saw palmetto which shows tentative benefit in those with mild to moderate androgenetic alopecia. There is no evidence for biotin. Evidence for most other produces is also insufficient. There was no good evidence for gingko, aloe vera, ginseng, bergamot, hibiscus, or sorphora as of 2011.

Many people use unproven treatments. Egg oil, in Indian, Japanese, Unani (Roghan Baiza Murgh) and Chinese traditional medicine, was traditionally used as a treatment for hair loss.

Research is looking into connections between hair loss and other health issues. While there has been speculation about a connection between early-onset male pattern hair loss and heart disease, a review of articles from 1954 to 1999 found no conclusive connection between baldness and coronary artery disease. The dermatologists who conducted the review suggested further study was needed.

Environmental factors are under review. A 2007 study indicated that smoking may be a factor associated with age-related hair loss among Asian men. The study controlled for age and family history, and found statistically significant positive associations between moderate or severe male pattern hairloss and smoking status.

Vertex baldness is associated with an increased risk of coronary heart disease (CHD) and the relationship depends upon the severity of baldness, while frontal baldness is not. Thus, vertex baldness might be a marker of CHD and is more closely associated with atherosclerosis than frontal baldness.

The objective assessment of treatment efficacy is very difficult and spontaneous remission is unpredictable, but if the affected area is patched, the hair may regrow spontaneously in many cases. None of the existing therapeutic options are curative or preventive.

In cases of severe hair loss, limited success has been achieved by using the corticosteroids clobetasol or fluocinonide, corticosteroid injections, or cream. The cream is not as effective and it takes longer in order to see results. Steroid injections are commonly used in sites where the areas of hair loss on the head are small or especially where eyebrow hair has been lost. Whether they are effective is uncertain. Some other medications that have been used are minoxidil, Elocon (mometasone) ointment (steroid cream), irritants (anthralin or topical coal tar), and topical immunotherapy ciclosporin, sometimes in different combinations. Topical corticosteroids frequently fail to enter the skin deeply enough to affect the hair bulbs, which are the treatment target, and small lesions typically also regrow spontaneously. Oral corticosteroids decrease the hair loss, but only for the period during which they are taken, and these drugs can cause serious side effects.

When alopecia areata is associated to celiac disease, the treatment with a gluten-free diet allows complete and permanent regrowth of scalp and other body hair in many people, but in others there are remissions and recurrences. This improvement is probably due to the normalization of the immune response as a result of gluten withdrawal from the diet.

Hair will not regrow once the follicle is destroyed. However, it may be possible to treat the inflammation in and around surrounding follicles before they are destroyed, and for this reason it is important to begin treatment as early as possible to halt the inflammatory process. Minoxidil solution (2% or 5%) applied twice daily to the scalp may be helpful to stimulate any small, remaining, unscarred follicles. The progression of hair loss is unpredictable. In some cases, progression is slow and there is always sufficient hair remaining to cover the affected scalp areas; in other cases, progression can be rapid and extensive.

Methotrexate and corticosteroids are proposed treatments.

Scalp cooling has specifically been used to prevent alopecia in docetaxel chemotherapy, although it has been found prophylactic in other regimens as well. Treatment effects may take time to resolve, with one study showing breast cancer survivors wearing wigs up to 2 years after chemotherapy.

Frontal Fibrosing Alopecia has been most often reported in post-menopausal women with higher levels of affluence and a negative smoking history. Autoimmune disease is found in 30% of patients.

Madarosis has different possible treatments and can be reversed if treated early enough. The treatments for madarosis are completely dependent upon the pre-existing condition. When suffering from blepheritis, antibiotics are used to combat the bacterial infection. People who are suffering from trichotillomania need to seek behavioral and psychological help. Many people look to hair transplant surgeries, especially in non-scarring cases. These surgeries are mainly used as a cosmetic reason rather than a medical one. There are also other treatments that can be used for cosmetic purposes.

There is currently researching being done to find more treatments dependent on the different pre-existing conditions.

Studies are being conducted in which madarosis can be related to malignancy. A study by Groehler and Rose found that there was a statistical significance between these two. They concluded that patients malignancy lesions on the eyelid have a higher chance of having madarosis than a patient with a benign lesion. They stated that despite the fact that it is significant, the absence of madarosis does not mean the lesion cannot be malignant.

In many leprosy cases, madarosis is a symptom or a quality after diagnosis. However, in India, leprosy is common and researchers report a case of madarosis before diagnosis of leprosy with no skin lesions, only madarosis. This allowed for quicker treatment.

A main reason many people have madarosis is due to the chemotherapy drugs. There was a clinical trial in 2011 that tested an eyelash gel called bimatoprost. This gel enhanced the eyelashes in quantity and thickness. They tested this on 20 breast cancer patients who were undergoing chemotherapy. Results seemed positive, in that the group of people who used the gel had growth of eyelashes after the chemotherapy drugs.

Alopecia universalis can occur at any age, and is currently believed to be an autoimmune disorder, in which a person's immune system attacks the hair follicles. Genetic factors may contribute to AU as approximately 20% of those affected have a family member with alopecia.

Many people use unproven treatments. There is no evidence for vitamins, minerals, or other dietary supplements. As of 2008, there is little evidence to support the use of lasers to treat male-pattern hair loss. The same applies to special lights. Dietary supplements are not typically recommended. A 2015 review found a growing number of papers in which plant extracts were studied but only one randomized controlled clinical trial, namely a study in 10 people of saw palmetto extract.

Minoxidil is a growth stimulant that stimulates already-damaged hair follicles to produce normal hair. Minoxidil does not, however, provide any protection to the follicles from further DHT damage. When a follicle is destroyed by DHT, minoxidil will no longer be able to have any more regrowth effects on that follicle. Other treatments include tretinoin combined with minoxidil, ketoconazole shampoo, spironolactone, alfatradiol, and topilutamide (fluridil).

Causes of noncicatricial alopecia include:

- Alopecia areata

- Anagen effluvium

- Androgenetic alopecia

- Dermatopathia pigmentosa reticularis

- Telogen effluvium

- Trichotillomania (Trichotillosis)

It is commonly seen with certain hair styles or braiding patterns that pull the hairline forcefully towards the vertex of the scalp, and has been reported more often in African American women (as some wear their hair tightly pulled back), in whom it can cause scarring. It has also been seen in female ballerinas, and in cultural traditions where the hair is voluntarily not cut in religious obeisance, the latter caused by progressively increasing weight of the hair itself. Traction alopecia is mechanical in cause, rather than androgenic, and treatment is typically not pharmaceutical. Management includes cessation of the chronic traction, cosmeses, with surgical restoration reserved for more severe cases.

Traction alopecia is a substantial risk in hair weaves, which can be worn either to conceal hair loss, or purely for cosmetic purposes. The former involves creating a braid around the head below the existing hairline, to which an extended-wear hairpiece, or wig, is attached. Since the hair of the braid is still growing, it requires frequent maintenance, which involves the hairpiece being removed, the natural hair braided again, and the piece snugly reattached. The tight braiding and snug hairpiece cause tension on the hair that is already at risk for falling out. Traction Alopecia is one of the most common causes of hair loss in African American women.

Sikh men are also susceptible to traction alopecia if the hair under the turban is tied too tightly for many years.

Other causes include:

- Hairstyle. Although the aforementioned style is one of the culprits, hairstyles such as dreadlocks and single (extension) braids can also have the same effect. Men and women who have suffered from traction alopecia have found that the hair loss occurs most at the hair line—primarily around the temples and the sides of their heads.

- Headgear. Compressive safety helmets worn tightly and closely to the scalp are a cause of traction alopecia. The lining of tightly fitted safety helmets like those worn for activities such as motorcycling, cycling, skiing and snowboarding are responsible for the constant rubbing and tugging of localised areas of the hair and scalp. Frequent wearers or those who use such helmets for prolonged periods seem more likely to suffer traction alopecia.

- Chemicals. A condition known as CCCA (central cicatricial centrifugal alopecia), seen almost exclusively in African American women, can cause extensive hair loss. It is caused by a combination of too much stress (traction) on the hair and the use of harsh relaxers and dyes.

Non scarring hair loss, also known as noncicatricial alopecia, is the loss of hair without any scarring being present. This is in contrast to scarring hair loss.

Lipedematous alopecia (also known as "Lipedematous scalp") is a disorder characterized by a thick boggy scalp and hair loss.

Hair diseases are disorders primarily associated with the follicles of the hair.

A few examples are

- Alopecia

- Bubble hair deformity

- Hair casts

- Hair loss

- hypertrichosis

- Ingrown hair

- Monilethrix

- Premature greying of hair

- Pattern hair loss

- Trichorrhexis invaginata

Many hair diseases can be associated with distinct underlying disorders.

Piedra are fungal diseases.

Hair disease may refer to excessive shedding or baldness (or both). Balding can be localised or diffuse, scarring or non-scarring. Increased hair can be due to hormonal factors (hirsutism) or non-hormonal (hypertrichosis). Scalp disorders may or may not be associated with hair loss.

Kinking hair (also known as "Acquired progressive kinking") is a condition primarily reposted in postpubescent males with androgenetic alopecia, presenting with gradual curling and darkening of the frontal, temporal, auricular, and vertex hairs which, under the microscope, show kinks and twists with or without longitudinal grooving.
