L-Lysine benefits to Stop Hair Loss and Promote Hair Growth


is a protein which forms the basic structure of hair follicle, along with keratinThe formation of collagen depends upon L-lysine. L-lysine is responsible for collagen formation since it helps absorb a vital mineral – calcium.


This is the major ingredient required for the production of collagen in hair, nails and skin. If you have a lack of L-lysine it stops the production of collagen. This, in turns can lead to massive hair loss. L-lysine also helps control androgenetic alopecia, which is male-pattern baldness. This causes hair loss at the top and front area of the head. 5-alpha reductase, which is a cause for male pattern baldness, converts the male hormone – testosterone – into DHT.


DHT is extremely harmful for hair growth because it stops it. L-lysine helps stop this process, with the result that DHT is not formed in the body. Therefore, L-lysine supplements are recommended to treat hair loss and other hair related disorders.
