Shampoos are easily the most sold products over the counter against hair loss. However, there is a huge mismatch between the amount of scientific literature available and the number of shampoos marketed for hair loss.
Hair Loss Treatment
The treatment of hair loss has been a mainstream idea since the end of the last century when it was first noticed that minoxidil, a drug initially developed to combat heart problems, could cause hair to grow. Over the past few years, several effective treatments for hair loss have been made available for both women and men.
Medication for Hair Loss Treatment
The use of medication to treat hair loss is, by far, the most standard method. Currently, the hallmark of medication treatment for hair loss is a reduction in the amount of dihydrotestosterone (DHT) in the body, which can be achieved by using finasteride.
Finasteride is one of the favorite medications among hair loss enthusiasts. According to the current guidelines, only the oral formulation of finasteride is approved for the treatment of hair loss. However, topical finasteride seems to offer similar effectiveness with a noticeably smaller possibility for side-effects.
Minoxidil was the first hair loss medication to be approved by the Food and Drug Administration (FDA). It also goes by the name Rogaine and is sold over the counter for the treatment of both male and female pattern hair loss. Currently, only the topical minoxidil formulation is approved for the treatment of hair loss.
Besides that, there is also nanoxidil – topical hair loss treatment product that is very similar to minoxidil, it only differs by its molecular weight. According to its manufacturer (D.S. Laboratories), it may be as effective as minoxidil but has a better penetration rate and no side-effects.
Low-level laser therapy
Laser treatment for hair loss, otherwise known as low-level laser therapy (LLLT), is a procedure that involves subjecting the scalp to infrared-emitting laser diodes in a therapy session that typically lasts between 8 and 30 minutes. The therapy can take place at a doctor’s office, but usually, you can do that at home with a laser comb or a cap.
Microneedling is a technique that is common among individuals who want to slow down the aging of the skin. The mechanism of this method is that it increases the production of collagen in the skin. The method first gained popularity in the 1990s when it was used to treat scars. Since then, studies have been published detailing how micro-needling can help in treating thinning hair and hereditary hair loss.
Moreover, as the small injuries heal, the skin produces a lot of collagen fibers, which strengthens the skin and enriches the hair follicle leading to hair regrowth.
DHT blockers (oral) are one of the few treatments for androgenetic alopecia (male and female pattern hair loss) that is approved by the FDA. However, there is a lot of misinformation floating around on the internet about the use and side effects of DHT blockers and many unsubstantiated claims about its alternatives.
