Which treatment suits very thick hair?

Indian straightening is the most powerful family in the catalogue and is intended for thick, dense, very curly hair. Brazilian straightening is the alternative when the client wants a suppler finish.

Which treatment for coloured or bleached hair?

Go for a gentle formula — Korean, French or tannin — with a lower iron temperature and a preliminary strand test on heavily bleached hair.

How many formulas does a salon need?

Three are enough for most requests: one powerful formula, one gentle formula and a hair botox for care services.

Is training required to offer these treatments?

No certification is required to order, but mastering the protocol determines the result. ULTRALISS Academy offers a one-day course dedicated to professional straightening.

Guide

How do you choose a professional straightening treatment?

Choosing a professional straightening treatment comes down to four things: hair density, chemical history, the result expected and the processing time available in the salon. ULTRALISS carries five families — Indian, Brazilian, Korean, French and tannin — all formaldehyde-free: thick, very curly hair calls for Indian or Brazilian, while fine or colour-treated hair is better served by Korean, French or tannin.

The main types of professional straightening

ULTRALISS carries five families of straightening treatment, each with its own shop category. Indian straightening is the most powerful and targets thick, dense, very curly hair. Brazilian straightening tames curly to frizzy hair with a supple finish. Korean straightening focuses on shine and movement on fine to medium hair. French straightening is the versatile option, suitable for colour-treated hair. Tannin straightening, plant-based, is intended for sensitised hair.

Every formula in the catalogue is formaldehyde-free and compliant with European regulations, including the treatments designed for the thickest hair.

How to choose between them

Four criteria are enough. Hair density: the thicker and denser the hair, the more powerful the formula. Chemical history: colouring, bleaching or a previous treatment call for a gentle formula. The expected result: light volume control or a markedly smooth finish. And the processing time you can devote in the salon.

When in doubt, start with the gentlest formula: a second pass is always possible, whereas damaged hair cannot be undone. On heavily bleached hair, a preliminary strand test and a lower iron temperature are essential.

Professional straightening for salons

A salon covers most of its clients with three formulas: a powerful one (Indian or Brazilian) for dense hair, a gentle one (Korean or tannin) for fine, coloured or sensitised hair, and a hair botox for pure care requests.

Plan the routine around the service too: preparation shampoo, heat protectant, mask and retail aftercare duo, plus the application equipment. ULTRALISS Academy runs a one-day course on performing a professional straightening treatment.
