Wet Hair & Breakage
A nuanced question that rarely deserves a universal rule.

What changes when hair is wet
Water plasticises the fibre. Wet hair stretches further before it breaks, and the swollen cuticle is more vulnerable to abrasion. Those two effects pull in opposite directions, which is exactly why the advice is contested.
Why "never detangle wet hair" is too strong
For many people with curly and coily patterns, detangling with conditioner and slip in the shower involves far less force than fighting dry tangles. For others, gentle dry or damp detangling is easier on the fibre.
What matters is the force applied, the tool, the amount of lubrication and how tangled the hair already is — not a slogan.
What generally reduces breakage regardless of wet or dry?
Working in sections, starting at the ends and moving upward, using enough slip, choosing a tool that doesn't catch, and stopping to separate a knot with your fingers instead of pulling through it.
Does rough towel-drying matter?
Friction on a swollen cuticle is a plausible contributor to surface wear. Blotting or squeezing with a smooth towel is a low-cost change if you're troubleshooting breakage.
Judge by results, not rules
If you're finding short broken pieces, change one variable at a time — the tool, the lubrication, the timing — and watch what happens over a few wash days. Your own record is better evidence than a general rule.
