Hair loss can be a frustrating and challenging experience, especially when it affects your self-esteem and confidence. Androgenic alopecia, also known as male or female pattern baldness, is one of the most common types of hair loss. This article will explore the causes, symptoms, and treatment options available for androgenic alopecia.
What is Androgenic Alopecia?
Androgenic alopecia is a genetic condition that affects both men and women. It is caused by a hormone called dihydrotestosterone (DHT), which shrinks hair follicles and leads to shorter, finer hair. Over time, the hair follicles become smaller and eventually stop producing hair altogether.
Symptoms of Androgenic Alopecia:
The symptoms of androgenic alopecia differ between men and women. In men, it usually starts with a receding hairline and thinning at the crown of the head. The hair loss gradually progresses, eventually leading to complete baldness. In women, hair loss is more diffuse and typically occurs on the top of the head. However, women rarely experience complete baldness.
Causes of Androgenic Alopecia:
A combination of genetic and hormonal factors causes androgenic alopecia. The condition is hereditary and can be passed down from generation to generation. It is also linked to the male hormone DHT. DHT is a byproduct of testosterone, and it binds to hair follicles, causing them to shrink and eventually stop producing hair.
Treatment Options for Androgenic Alopecia:
There are several treatment options available for androgenic alopecia. However, it is essential to note that the condition has no cure. The treatments can slow down the progression of hair loss and, in some cases, stimulate hair growth.
Minoxidil:
Minoxidil is a medication used for over 30 years to treat hair loss. It was first used as an oral medication to treat high blood pressure, but researchers discovered it also stimulated hair growth. Today, minoxidil is available in a topical solution applied directly to the scalp. It is available over the counter and is approved by the FDA for treating androgenic alopecia.
Minoxidil increases blood flow to the hair follicles and stimulates hair growth. It is believed to widen the scalp’s blood vessels, allowing more oxygen, blood, and nutrients to reach the hair follicles. This increased blood flow can lead to thicker, fuller hair over time.
Minoxidil is available in two strengths – 2% and 5%. The 5% solution is more effective than the 2% solution but can also cause more side effects. Common side effects of minoxidil include scalp irritation, dryness, and itching. In rare cases, minoxidil can cause more severe side effects such as chest pain, rapid heartbeat, and dizziness.
It is important to note that minoxidil does not cure androgenic alopecia. It can slow down the progression of hair loss and stimulate hair growth, but it does not work for everyone. It can take several months to see results, and hair growth may be gradual. It is essential to continue using minoxidil as directed to see the best results.
Finasteride:
Finasteride is an oral medication that is used to treat androgenic alopecia in men. It works by blocking the conversion of testosterone to DHT, which shrinks hair follicles. Finasteride is available only by prescription and is not approved for use in women.
Finasteride was first approved by the FDA in 1992 for the treatment of benign prostatic hyperplasia (BPH), a condition in which the prostate gland becomes enlarged. Researchers discovered that finasteride also had an effect on hair growth, and it was subsequently approved for the treatment of androgenic alopecia.
Finasteride works by inhibiting the enzyme 5-alpha reductase, which converts testosterone to DHT. DHT is the hormone that shrinks hair follicles and leads to hair loss in androgenic alopecia. By blocking the production of DHT, finasteride can slow down the progression of hair loss and even stimulate new hair growth.
Finasteride is available in a 1mg tablet that is taken once daily. Common side effects of finasteride include decreased libido, erectile dysfunction, and decreased ejaculate volume. In rare cases, finasteride can cause more severe side effects such as allergic reactions, breast cancer, and depression.
It is important to note that finasteride is not a cure for androgenic alopecia. It can slow down the progression of hair loss and stimulate hair growth, but it does not work for everyone. It can take several months to see results, and hair growth may be gradual. Women are not recommended to use finasteride as it can cause birth defects in male fetuses if taken during pregnancy. Finasteride is only approved for use in men.
Hair Transplant:
A hair transplant is a surgical procedure that involves moving hair from the back and sides of the head to the balding areas. The procedure is effective in restoring hair growth in the transplanted area, but it can be expensive and requires multiple sessions.
Hair transplant surgery has been around for over 60 years, but it has evolved significantly in recent years. Today, there are two main types of hair transplant surgery – follicular unit transplantation (FUT) and follicular unit extraction (FUE).
FUT, also known as the strip method, involves removing a strip of skin from the back of the head and dividing it into individual hair follicles. These follicles are then transplanted into the balding areas of the scalp. FUE, on the other hand, involves removing individual hair follicles from the back and sides of the head using a punch tool. These follicles are then transplanted into the balding areas of the scalp.
Hair transplant surgery is usually performed under local anesthesia and can take several hours to complete. The procedure can be painful, and recovery can take several days to several weeks. After the surgery, the transplanted hair will fall out within a few weeks, but new hair growth should start within a few months. It can take up to a year to see the full results of the surgery.
Hair transplant surgery is expensive and is not covered by insurance. The cost can range from Rs. 50,000 to Rs. 200,000, depending on the extent of the surgery. In addition, multiple sessions may be required to achieve the desired results.
Low-Level Laser Therapy (LLLT):
LLLT is a non-invasive treatment that involves exposing the scalp to low-level laser light. The therapy is thought to increase blood flow to the hair follicles and stimulate hair growth. LLLT can be done at home using a laser cap or in a doctor’s office using a laser device.
LLLT works by stimulating the hair follicles to produce more energy, which can lead to thicker, fuller hair. It is believed that laser light can penetrate the scalp and reach the hair follicles, which stimulates cell metabolism and increases blood flow. This increased blood flow can lead to improved hair growth over time.
LLLT is a painless and non-invasive treatment that does not have any known side effects. However, it can take several months to see results, and hair growth may be gradual. It is essential to continue using LLLT as directed to see the best results.
Conclusion:
Androgenic alopecia is a common hair loss condition that affects both men and women. It is caused by a combination of genetic and hormonal factors, and there is no cure for the condition. However, there are several treatment options available that can slow down the progression of hair loss and stimulate hair growth. Minoxidil and finasteride are FDA-approved medications that can be effective in treating androgenic alopecia, and hair transplant and LLLT are other treatment options available. It is important to consult with a dermatologist or hair loss specialist to determine the best treatment plan for your individual needs.
