Why didn't my hair straightening treatment work or why didn't it turn out well?

In 99% of cases, straightening fails because the right iron was not used or the correct temperature was not used .


For the product to activate and seal correctly, it is ESSENTIAL to use:

Iron with 100% TITANIUM plates (not ceramic, not tourmaline, not coated)
Minimum temperature of 230°C (450°F) — always at MAXIMUM power


⚡ If you use our Lizze Extreme iron, it should be set to 250°C

If the temperature is low or the straightener is not titanium, the product will not seal and the hair will not be straight , even if you have done the rest of the process correctly.

How do I use it?

Rebuild and straighten your hair at home with a quick and precise protocol for a polished, shiny, and frizz-free finish.

Step 1: Prepare
Wash with Pre-Treatment Shampoo 2–3 times until all residue is removed. Dry completely (preferably with cool air).

Step 2: Apply
Shake the product. Divide into quadrants and apply with a brush to thin strands starting at the nape of the neck, leaving 1 cm from the roots . Avoid excess product and the scalp.

Step 3: Rest
Leave to act for 15–20 minutes in the air .

Step 4: Dry and seal
Dry on low power with hot air and a brush. Straighten at 230°C : 25–30 passes on roots/mid-lengths and 15–20 on ends .

Step 5: Wash and finish
After 20 minutes , remove completely with your usual wash (shampoo + mask).

Segui las instrucciones al pie de la letra, no es la primera keratina que aplico, la verdad que muy bien alisa totalmente y deja esa apariencia de mas cabello, pero no deja ese brillo que he visto en otras keratinas es fácil de aplicar y secar asi que muy bien, volvería a comprar
