Overview

OLLY Heavenly Hair gummies contain biotin and zinc, which are known to support hair health. However, the inclusion of keratin, amla extract, and horsetail extract lacks strong scientific backing for promoting hair growth or improving hair quality in healthy individuals. The zinc dosage is also relatively low, further limiting the potential effectiveness of this product.

The Good

Contains biotin at a high dose (3000 mcg per serving)

Includes zinc, an essential mineral for hair health

Convenient and palatable gummy form

The Bad

High sugar content (2g added sugars per serving)

Limited evidence for efficacy of keratin, amla extract, and horsetail extract for hair health in healthy individuals

Potential for biotin interference with laboratory tests

Is it for you?

Best For: Individuals looking to support hair health, strength, and growth; those who prefer gummy supplements.
