How can you tell if your hair is damaged?

You can tell if your hair is damaged by looking for signs like dryness, dullness, frizz, split ends, and excessive breakage, and feeling for a rough, brittle, or mushy texture and a lack of elasticity (hair snaps instead of stretching). Damaged hair struggles to retain moisture, leading to tangles and making it hard to style, and it often appears uneven and frayed, as the protective outer cuticle is lifted or stripped away.

Can you heal damaged hair?

You can't fully "heal" permanently damaged hair because the keratin structure is dead, but you can significantly improve its appearance and health by using targeted treatments (like bond builders, masks, protein), adopting gentle habits (less heat, gentle brushing, trims), and reducing further stress, allowing new, healthy hair to grow in strong over time. 

How to tell if hair is damaged or just frizzy?

Frizz can be from dryness (needs moisture/hydration), while damage often involves breakage, split ends, dullness, and rough texture from compromised cuticles, but frizz is a symptom of both; check for tiny nubs/breaks for damage, or just poofiness for dryness, and use the stretch test: healthy hair stretches and bounces back, damaged hair snaps easily, says Aveda and Dove.
