Are supplements bad for hair?
Which is better for hair biotin or keratin?
Biotin supplements claim they “support” healthy skin, hair, and nails. But unless you’re deficient in biotin, these supplements aren’t going to do much. (And biotin deficiency is extremely rare.) These supplements are generally a waste of money.
Gummy vitamins tend to lose their potency more quickly than pills, meaning that it’s harder to predict how long gummies will last on the shelf. To make up for this, some manufacturers include extra doses of vitamins in their gummies, which can cause problems if you take in too much of these nutrients.
As a result, keratin would help in making frizzy hair smoother, and also improve the shine and lustre of dull hair. On the other hand, biotin is a type of vitamin. That is why a biotin shampoo would help arrest hair thinning and hair fall, and even stimulate hair growth.
