Is this shea butter hair product safe for sensitive scalps or dry hair?

The high content of natural oils and shea butter makes it excellent for dry or brittle hair, providing deep hydration, but the inclusion of fragrance, BHT, imidazolidinyl urea and methylisothiazolinone means it may trigger irritation on highly sensitive scalps; a patch test is recommended before regular use.

What is the role and benefit of shea butter in this formulation?

Shea butter (Butyrospermum Parkii butter) acts as a rich emollient that penetrates the hair shaft, sealing in moisture, smoothing cuticles, and reducing frizz, while also providing antioxidants that protect against environmental stress.

How often should this conditioner be applied, and does it contain any controversial chemicals?

It is designed as a rinse‑out conditioner applied after shampooing, typically once per wash; the formula includes controversial ingredients such as BHT (a synthetic antioxidant), imidazolidinyl urea and methylisothiazolinone (preservatives) as well as hexyl cinnamal (fragrance), which some consumers may wish to avoid.
