Why Your Curly Hair Needs Protein: The Science Behind Stronger, Healthier Curls

If your curls have lost their bounce, feel limp or overly soft — you might be dealing with protein deficiency. While moisture is vital, protein is just as crucial to maintain structure, shape, and strength in curly hair.

Here’s why protein treatments matter — and how to incorporate them into your routine.

What Does Protein Do for Hair?

Hair is made up of keratin, a natural protein. Frequent washing, heat styling, coloring, or even humidity can weaken your hair’s internal structure, leading to breakage, frizz, and undefined curls.

A protein treatment temporarily fills in gaps in the hair cuticle, restoring strength and elasticity.

Signs Your Curls Need Protein:

• Hair feels mushy or overly soft
• Loss of curl pattern
• Excessive shedding or breakage
• Frizz that won’t go away with moisture

How Often Should You Use Protein on Curly Hair?

For most curly hair types, once every 2–4 weeks is ideal. But always follow with moisture — balance is key.
