Is this product safe for sensitive scalps or dry, damaged hair?

The serum contains silicones and conditioning agents that smooth dry or damaged hair, but the presence of fragrance, phenoxyethanol and the preservatives methylisothiazolinone and methylchloroisothiazolinone can be irritating for very sensitive scalps; a patch test is recommended for users with known sensitivities.

What benefits does panthenol provide in this hair serum?

Panthenol, a provitamin B5, penetrates the hair shaft to improve moisture retention, enhance elasticity and add subtle sheen, helping to reduce breakage and leave the hair feeling softer and more manageable.

How often should the Color Boost minute radiance treatment be applied, and does it contain any controversial ingredients?

The serum is intended for daily use after washing, applied to damp hair and distributed evenly, and it includes silicone polymers, fragrance, phenoxyethanol and the preservatives methylisothiazolinone and methylchloroisothiazolinone, which are often noted by consumers as potential irritants.
