Best Natural Hair Growth Supplements

Hair supplements work differently from shampoos.

A shampoo acts externally on the scalp and hair. A supplement supplies nutrients and botanical ingredients through the diet.

That doesn't mean taking more vitamins automatically makes hair grow faster. If you already receive sufficient amounts of a nutrient, taking excessive amounts is unlikely to provide additional hair benefits and may sometimes be harmful.

Instead, look for sensible formulations built around relevant nutrients and ingredients.

Ingredients to look for

Biotin contributes to the maintenance of normal hair.

Vitamin D has important roles throughout the body, and low vitamin D status has been investigated in relation to several forms of hair loss.

Pumpkin seed is increasingly used in botanical hair supplements.

Saw palmetto is frequently included in supplements marketed toward people concerned about androgen-related thinning, although evidence remains more limited than for established medical hair-loss treatments.

Amla and other Ayurvedic botanicals have a long history of use in traditional haircare, although traditional use should not be confused with clinical proof of hair regrowth.
