Overview

The Difeel Biotin Root Stimulator relies on biotin and hydrolyzed proteins, ingredients with limited direct evidence for stimulating hair growth via topical application in non-deficient individuals. While proteins can improve hair conditioning, their growth-promoting effect on the roots is not well-established. The overall effectiveness for its primary marketed claims is questionable due to a lack of strong scientific backing for the formula's components in a topical context.

The Good

Menthol provides a refreshing sensation which some users may find pleasant.

Hydrolyzed proteins may offer some conditioning benefits to existing hair strands, improving texture and reducing breakage.

Contains ingredients that suggest an intent to nourish hair, even if direct efficacy for root stimulation is limited.

The Bad

Biotin's topical efficacy for hair growth is not well-supported by scientific evidence.

Contains Alcohol Denatured, which can be drying and irritating to the scalp as a leave-in product.

Contains formaldehyde-releasing preservatives (Diazolidinyl Urea, Iodopropynyl Butylcarbamate) which are common allergens and irritants.
