IS there a Treatment for Hair loss? Part 2

Medications

Despite all the razzmatazz about medications by the drug industry, they are all ineffective and expensive. It is the very rare individual who will regain hair growth after use of these medications and this is more pure luck than any credit to the medications. None of these medications work if there is baldness. It is hard to find any one individual (who is honest) to have any sort of significant hair growth after using these medications.

The drugs approved for the treatment of alopecia are:

Minoxidil (Rogaine). This medication was associated with a lot of hype but never lived up to its expectations. It can be used to treat both types of alopecia. It comes as a liquid and is applied on the scalp twice a day. It is available over the counter in strengths of 2-5%. It is approved for the treatment of androgenic alopecia and alopecia areata. It is difficult to find anyone (at least those not paid by the industry) who has evidence of any hair growth after use of this medication.

The industry claims that new hair after application of minoxidil is thinner and shorter than previous hair. The hair growth stops once the use of the mediation is stopped. The only side effect is an irritation or dryness of the scalp.

Finasteride (Propecia). Finasteride is another medication which has been approved for male pattern baldness. It is taken as an oral pill. Some individuals do claim hair growth and the results take at least 2-4 months to show. Finasteride works by inhibiting the conversion of the male testosterone into dihydrotestosterone, a hormone that decreases hair growth. For some men there may be some hair growth but the medication also causes a decrease in sex drive- a high price to pay for some hair follicles. As with minoxidil, the benefits of Finasteride stop if you stop using it. The drug is only approved for use in men.

Corticosteroids. For alopecia areata, some physicians may inject corticosteroids. These injections are performed every month for a few months. Some physicians also recommend topical corticosteroid creams. The results are not great. Some individual show a response and many do not. In most cases of alopecia areata, the hair growth will recover after some time and the need for corticosteroid injection is questionable. Corticosteroids do nothing for androgenic alopecia.

Anthralin (Drithocreme). Available as either a cream or an ointment. This is a tar like chemical which is used in the treatment of psoriasis. It is not effective in all individuals and the results are mild, at best. The drug also stains bed sheets, clothes and makes a real mess.

Herbs/nutrients; everyday on the internet and popular medical magazines, there are new drugs/nutrients advertised as the latest to cure hair growth. Individuals from every ethnic background have their own version of folklore tales and myths about hair growth. The things recommended for hair growth are wild and beyond the realms of one’s imagination- from crow’s feet, bears penis, scorpions arse, snakes gall bladder, meditation, yoga, et etc. There is not one iota of proof that any of these work. There is no herb or nutrient that can grow any hair.

The hair growth industry is a big scam and the best advice is to avoid these products and save one’s money.

Myths about Hair loss

Hair loss has been associated with more myths and folklore all which are based on superstition and ignorance. Everyone has an idea about how hair loss occurs. The internet is inundated with so called hair experts who speculate on why hair loss occurs.

Some of the nonsense speculated about why hair loss occurs include the following: Excess shampooing (esp. with head and shoulders shampoo), daily washing of hair, the type of shampoo, use of hair dryer, the type of soap, use of towel, the hardness or softness of the water, the geographical area where one lives, ethnicity, eating herbs, cleansing the bowels once a week, not cleaning the backside after poop and even excessive masturbation has been blamed on hair loss.

Like I mentioned before-bad genes, bad hormones and a lot of bad luck are the real answers to hair loss.
How does hair loss occur?

At any one point in time, the majority of hair on the scalp is in a growth phase anagen). This growth phase lasts anywhere from 2-6 years. About 10% of the scalp hair is in a resting phase (telogen) which lasts about 2-4 months. After this time, the hair is shed and a new cycle begins. Most individuals shed about 30-150 hairs everyday. After a single hair is shed, a new hair follicle replaces the same hair and the cycle begins again. Most hair grow at about 10 mm per month

In any individual who sheds hair faster than the hair regrowth, then baldness will occur. Initially the hair loss is gradual and then suddenly increases.
Types of hair loss

Hair loss is known as alopecia. The most common type of hair loss is known as male pattern baldness (androgenic alopecia). This is the most common type of hair loss in men and affects nearly 40-50% of males. The hair loss is permanent. The other type of hair loss is called alopecia areata- which commonly affects hair growth on different parts of the body besides the scalp and the disorder is temporary.

Two Major Causes of Hair Loss Part 1

Male pattern baldness (Androgenic alopecia)

Those individual who develop androgenic alopecia may experience hair loss as early as the early teenage years. The hair loss gets more progressive through the ensuing years and the results become more noticeable on the scalp. The hair loss typically begins at the temples and crown. The end result of the hair loss is partial or complete baldness by the 30s to early 40s. This is an irreversible process-permanent.

The androgenic variety of alopecia has a familial connection but the actual pattern of genetic inheritance remains unknown. This type of hair loss is common in both males and females, but females rarely go bald. If anyone in the family is bald, then one can rest assured that other male members of the family will have the same unfortunate event occur sometime. In most cases, when there is male pattern baldness in the family, the hair loss typically occurs at a much younger age and a lot faster.

Alopecia areata

Alopecia areata is associated with temporary hair loss from the face and other areas of the body. The condition happens suddenly and results in patchy hair loss. The hair loss may be on the face or parts of the scallop. The area becomes completely devoid of hair follicles and appears smooth and white.

The cause of alopecia areata is unknown. But there are many speculations. Some claim that it is related to stress, a viral infection and other claim that it is autoimmune (your own body’s cell react and kill the hair cells) or bad luck. The hair loss occurs suddenly and most men are in good health and young.

It is not known if there is a genetic link with alopecia areata. The good thing about the disorder is that the condition is temporary and the hair does grow back. In most cases, the hair loss persists for a few months and then all of a sudden the hair reappears. The condition can recur a few times.
