Saw Palmetto For Hair loss. This video is about whether you can use Saw Palmetto for hair loss. Dr Sam will talk about the current medical evidence for using Saw Palmetto to treat hair loss.
Male pattern baldness is the most common type of hair loss that develops in men. The age it first starts is variable, where about 30% of men aged 30 years will have significant balding. Nearly all men have some hair loss by the age of 60 years. Usually it will take 15-25 years to go completely bald, but for some men it will take less than 5 years.
HOW DOES HAIR LOSS START:
Hair begins to thin at the temples and on the top of the head. A bald patch gradually develops in the middle of the scalp. Over time, the sides and crown balding gradually enlarge and join together, leaving a patch at the front.
HAIR LOSS CAUSE:
In men with male pattern baldness testosterone levels are normal. Cells in the skin (scalp) convert testosterone to another hormone dihydrotestosterone. For unclear reasons, affected hair follicles become more sensitive to dihydrotestosterone and shrink. When the follicles shrink, each new hair is thinner and grows for a shorter amount of time until the hair does not grow out to the skin surface. It is unknown why only the scalp is affected and not facial or body hair. This condition is inherited, and various genes have been identified.
WHAT IS SAW PALMETTO:
Saw palmetto is an extract from the berries of the palm tree saw palmetto (also called Serenoa Repens, serenoa serrulata or sabal serrulata). The plant is a native of West Indies and is grown in plenty on the Atlantic southeast coast of North America. The extract of these berries is easily available and inexpensive.
HOW DOES SAW PALMETTO WORK?
Serenoa repens is one among the many naturally occurring 5 alpha reductase (5aR) inhibitors.
SIDE EFFECTS OF SAW PALMETTO:
Side effects are said to be uncommon. The most common side effect is mild stomach discomfort which can be alleviated by taking it after food, also breast tenderness and a loss in sex drive (libido) have been reported.
