(8) A straightening iron is then applied to each of the locks 1 to 6 by making continuous passes along the locks.

(9) The locks are left to stand at room temperature for a time of 24 hours before performing a first sensory evaluation of the disentangling (measurement T0).

(10) Lock 8 is placed under the exposure of a UV lamp (λ=365 nm, 100 Watts) for 5 minutes, then the lock is left to stand at room temperature for a time of 24 hours before performing a first sensory evaluation of the disentangling (measurement T0).

(11) Lock 9 is placed under the exposure of a LED lamp (17 Watts) for 10 minutes on each side, then the lock is left to stand at room temperature for a time of 24 hours before performing a first sensory evaluation of the disentangling (measurement T0).

(13) After drying, disentangling tests with a comb were performed after immersion for 10 seconds in water, by passing a plastic comb through five times.

(14) 2.3. Procedure—Shampoo Resistance

(15) Shampoo is applied to each of the locks, at a rate of 1 g per 2.8 g of locks, and the locks are then massaged for a time of 10 seconds. The shampoo is left on for a time of 3 minutes, before rinsing with water at a temperature of 37° C., 10 passes being performed. The lock is then dried.

(16) This protocol is repeated five times and a second sensory evaluation of the disentangling is performed (measurement T5).
