Knowing how ingredients interact with hair helps salons choose effective products. This article breaks down key components and their roles.

Moisturizers and Humectants

These ingredients help retain water in the hair shaft to prevent dryness.

Examples include glycerin and panthenol which attract and hold moisture.

Proteins and Strengthening Agents

Proteins like keratin rebuild damaged hair by filling in gaps along the strand.

They improve elasticity and reduce breakage when used correctly.

Silicones and Conditioning Components

Silicones smooth hair cuticles for shine and reduce frizz temporarily.

They also provide a protective barrier against environmental stress.

Potential Irritants and Allergens

Some chemicals may cause sensitivity and should be considered when recommending products.

Understanding ingredient lists helps anticipate client reactions.
