Pitak atau Botak ??


Bila kita berbicara tentang kebotakan, maka dalam dunia medis, banyak jenis kebotakan dengan berbagai gambaran klinis dan penyebab. Artikel ini tidak akan membahas tentang kebotakan yang menyeluruh, atau kebotakan pada pria~ yang akan kita bahas di artikel lain~. Kita akan membahas tentang kebotakan setempat, atau yang biasa dikenal sebagai PITAK :) 

Tidak banyak pasien yang datang dengan pitak. Tapi karena pitak ini sangat mengganggu pasien, terutama bila pasiennya sudah dewasa, baik wanita maupun pria, biasanya datang dengan stress dan harap harap cemas kapan akan tumbuh kembali.. 

Artikelnya belum sempat saya translate, jadi versi bahasa indonesianya nyusul ya..  :) 

Alopecia Areata

Alopecia areata (AA) causes hair loss in small, round patches that may go away on their own, or may last for many years. Some people with AA (about 5%) may lose all scalp hair (alopecia totalis) or all scalp and body hair (alopecia universalis). The immune system, for unknown reasons, attacks the hair root and causes hair loss.
Who gets AA?
AA occurs world-wide in both genders and in every ethnic group. Children and young adults are most frequently affected, but persons of all ages are susceptible. One in five persons with AA has a family member who also has the disease.
What are the signs and symptoms of AA?
AA usually begins with one or more small, round, coin-size, bare patches. It is most common on the scalp, but can involve any hair-bearing site including eyebrows, eyelashes, and beards. Hair may fall out and regrow with the possibility of full hair regrowth always present. AA usually has no associated symptoms, but there may be minor discomfort or itching prior to developing a new patch. Nails may have tiny pinpoint dents and may rarely become distorted.
What causes AA? AA is not contagious. It is an autoimmune disease in which the body’s immune system attacks itself, in this case, the hair follicles. The cause is not known. A person’s particular genetic makeup combined with other factors triggers AA.

What tests are done to confirm AA?
Although your dermatologist may know by examining your scalp that you have AA, occasionally, a scalp biopsy is helpful in confirming the diagnosis.
Is this a symptom of a serious disease?
AA is not a symptom of a serious disease and usually occurs in otherwise healthy individuals. Persons with AA may have a higher risk of atopic eczema, asthma, and nasal allergies, as well as other autoimmune diseases such as thyroid disease (Hashimoto’s thyroiditis), and vitiligo. Family members may also have atopic eczema, asthma, nasal allergies, or autoimmune diseases (i.e. insulin-dependent diabetes, rheumatoid arthritis, thyroid disease, or systemic lupus erythematosus).
Will the hair grow back?
Yes, it is likely that the hair may regrow, but it may fall out again. The course of the disease varies from person to person, and no one can predict when the hair might regrow or fall out again. This unpredictability of AA, and the lack of control over it, makes this condition frustrating. Some people lose a few patches of hair, the hair regrows, and the condition never returns.

Other people continue to lose and regrow hair for many years. The potential for full regrowth is always there, even in people who lose all the hair on their scalp and body (alopecia totalis/universalis). Hair could regrow white or fine, but the original hair color and texture may return later.

What treatments are available?
There is no cure for AA. While treatments may promote hair growth, new patches of hair loss may continue to appear. The treatments are not a cure. Only the body, itself, can eventually turn off the condition.


Corticosteroids — are anti-inflammatory drugs that suppress the immune system. They can be given as injections into the areas of hair loss, taken as pills, or rubbed into affected areas. Steroid injections every 3-6 weeks are given directly into hairless patches on the scalp, eyebrow, and beard areas. Hair growth usually begins approximately 4 weeks after the injection. Steroids that are rubbed directly into affected areas are less effective than injections. Corticosteroids taken by mouth have potential side effects. They are not used routinely, but may be used in certain circumstances.
Topical minoxidil 5% solution — may promote hair growth in alopecia areata. Minoxidil 5% solution applied twice daily to the scalp, brow, and beard areas may promote hair growth in both adults and children with AA. New hair growth may appear in about 12 weeks.

Anthralin — is a synthetic tar-like substance that alters immune function in the affected skin. It is applied for 20 to 60 minutes (“short contact therapy”) and then washed off to avoid skin irritation. Irritation is not needed in order to stimulate hair regrowth in AA. 
Combinations of these treatments may add to the effectiveness. Hopefully, new hair growth will appear in 8 to 12 weeks.
Other Alternatives
Wigs, caps, hats, or scarves are important options. Wearing a head covering does not interfere with hair regrowth. This may be a good choice for people with extensive scalp hair loss who do not have enough hair to cover it.

Will alopecia areata affect life?
It is reassuring that alopecia areata does not affect general health, and should not interfere with your ability to achieve all of your life goals at school, in sports, in your career, and in raising a family.
The Future
Immunomodulators and other therapies are being explored and researchers continue to advance the treatments for AA.
