Expert note

Not recommended. Contains multiple concerning preservatives: DMDM Hydantoin (formaldehyde releaser), plus MI/MCI sensitizers. Also has Cocamide MEA (potential irritant) and Sodium Sulfate. Despite having good proteins (Keratin, Elastin, Wheat) and Coconut Oil, the preservative system makes this a poor choice. Seek alternatives without formaldehyde releasers.

Patch test before full use if you have fragrance allergies or reactive skin.
