I usually consume biotin with 5000mcg strength. These capsules have 10000 mcg strenght, not a issue to people requiring smaller dose as the body absorbs only what is required for you and the rest is flushed out of the system. Biotin is a safe and nontoxic vitamin. It has not been associated with any serious side effects, even in large doses.
Other ways it helps is by breaking down food into sugar that your body can use for energy. Biotin is important not just for healthy skin and nails, but it also keeps your eyes, liver, and nervous system working properly.
When I started using this I definitely see the difference. I also use hair growth shampoos along with the supplement so they do help!
My existing hair is growing longer and feels thicker. The areas on my scalp with less hair have been steadily growing in with new hair.
It has not been an overnight process. It takes at least a week/weeks to visually notice changes but you’ll definitely see the change after just one bottle.
