Biotin Boost Leave In Spray

Hask Beauty's Biotin Boost Leave-In Spray is a lightweight mist treatment designed to support thinning, fragile hair and improve manageability between washes. The spray absorbs quickly with a non-greasy finish and suits fine-to-medium strands seeking strength and shine. Fragrance-free and vegan-friendly options make it appealing to scent-sensitive users and those avoiding animal-derived ingredients.
