Editor's note

Hair breakage is structural failure, not surface failure. It happens when the cortex — the inner protein architecture of the strand — has been compromised by chemistry, heat, mechanical stress, or some combination of all three. The break site is rarely where the damage started.

What breakage actually is

Hair breakage is the snapping of the shaft somewhere between root and tip — distinct from shedding, which is loss at the follicle. The break point is usually where the cortex has been weakened by chemical swelling, heat-induced protein denaturation, or chronic friction and tension.

Myth, meet fact

• Myth: Breakage means your hair is too dry. Fact: Protein-depleted hair can be slippery and soft while still snapping constantly.
• Myth: Trimming stops breakage. Fact: Trimming removes the evidence. The causes continue until you address them.
• Myth: Protective styles always protect. Fact: A too-tight or too-long-worn protective style causes breakage at the hairline.

The beginner's path

1. Shedding vs breakage — how to tell the difference (3 min)
2. The elasticity test — what it tells you (4 min)
3. Protein treatments: what, when, how much (6 min)
4. Tension: the invisible cause of breakage (5 min)
5. Heat damage and breakage — a six-week recovery plan (4 min)

Treatment by damage source

Protein treatment: for elasticity loss and chemical damage. Bond builder: for bleach and lightening damage. Deep conditioner: always pair with protein. Strengthening serum: daily on ends. Protective style: during recovery. Scalp treatment: when breakage clusters at the hairline.
