What is the protein-moisture balance?

Healthy hair needs both protein (for strength and structure) and moisture (for flexibility and softness). Too much protein makes hair stiff, dry and brittle. Too little protein makes it mushy, limp and prone to stretching and breakage. The balance depends on your hair type and history.

How do I know if I need protein or moisture?

Stretch a wet strand gently. If it stretches a lot and does not spring back, you need protein. If it barely stretches and snaps quickly, you need moisture. If it stretches slightly and springs back, the balance is good. Also observe: mushy/limp = needs protein; straw-like/brittle = needs moisture.

Can I use protein and moisture treatments together?

Yes, many products contain both. For best results, alternate between protein and moisture treatments. After a protein treatment, always follow with a moisture treatment to maintain softness. Some bond-repair treatments address both simultaneously.

How We Calculate This

Scoring

Each factor (porosity, texture, elasticity, chemical history, condition, heat usage) contributes to both protein and moisture need scores on a scale of 0-10.

Balance Assessment

If scores are within 1.5 points, the balance is good. A higher protein score indicates protein deficiency. A higher moisture score indicates moisture deficiency.
