While biotin is a type of vitamin that plays a functional role in hair growth, there are other vitamins that can help improve the overall health of your hair. Vitamin E is one such key vitamin that acts as an antioxidant and helps to reduce the oxidative stress on your scalp. This greatly affects hair growth, and this was proven by a study published in the Tropical Life Sciences Research journal (2). Another vitamin that is useful is vitamin C. It removes the dead cells build-up from the scalp and unclogs the hair follicles. This can improve hair growth as well (3). Vitamin C tablets can be added to a carrier oil and used to massage the scalp. Internal supplements of both these vitamins also help.
2. High-tech regrowth therapies. Laser treatments ($200 and up) expose hair to low levels of laser light, which boosts hair growth by increasing the amount of adenosine triphosphate (ATP) in hair follicles. ATP provides energy to hair-follicle cells, so the more of it that’s around, the more energy hair follicles can use to grow your hair. Sadick says three months of weekly sessions are best when you’re kick-starting a hair-loss treatment.
Hair loss comes in different forms. Whether hair loss is caused by genetics or a traumatic life event, it can take a huge toll on one's self-esteem. The vast amount of hair-loss products available can make it difficult to discern what works and what doesn't. We poured over dozens of user and owner reviews and clinical studies to bring you a definitive list of the top hair-loss products on the market.
There’s no cure for baldness, but there are ways to hold on to what you've got. The six dermatologists and the clinical studies point to three methods: minoxidil, laser treatments, and prescription finasteride. The key is finding the combination and hair loss regimen that works for you. A doctor is your best bet for that kind of guidance — but we found a few trustworthy products that will work for most people.
In either sex, hair loss from androgenetic alopecia occurs because of a genetically determined shortening of anagen, a hair's growing phase, and a lengthening of the time between the shedding of a hair and the start of a new anagen phase. (See "Life cycle of a hair.") That means it takes longer for hair to start growing back after it is shed in the course of the normal growth cycle. The hair follicle itself also changes, shrinking and producing a shorter, thinner hair shaft — a process called "follicular miniaturization." As a result, thicker, pigmented, longer-lived "terminal" hairs are replaced by shorter, thinner, non-pigmented hairs called "vellus."
