Brazil Protein Supreme Repair Shampoo (300 ml) is the wash step of the Supreme Repair line, printed for dry and chemically treated hair. The front names castor oil and vitamin E, and both are on the list: tocopherol 10th, castor 12th. You apply it to wet hair, massage and rinse; the pack leaves the second wash to your judgement. The conditioning step of the same line is the Supreme Repair Moisturizing Cream 250 g.

What the ingredient list shows

The list opens with water and disodium laureth-sulfosuccinate, the main cleansing agent, followed by cocamide DEA and cocamidopropyl betaine. Hydrolyzed silk and panthenol come 6th and 7th, ahead of the fragrance; the castor and rosehip oils sit further down. What you control is the number of washes: both sets of directions say to repeat if necessary.

What to expect

Clean hair that is ready for the conditioning step. That is the whole job of this bottle, and we would not ask more of a shampoo on chemically treated lengths.

Who it is for

• Dry and chemically treated hair, as the front prints it
• The wash before the cream of the same line
• Salons that want the wash station and the retail shelf on one line

Who it is not for

• Clients sensitive to methylchloroisothiazolinone or methylisothiazolinone: the preservative pair is 15th on the list
• Clients sensitive to fragrance: parfum is 8th on the list
• Clients who avoid animal-derived ingredients: hydrolyzed silk is 6th on the list

Professional tip

On chemically treated lengths, do not scrub the ends. Lather at the roots and squeeze the foam through on the rinse. Wet, treated hair is at its most fragile when it is rubbed, and the lengths come clean from the rinse alone. That is the habit we train first on this line.

How to use

The bottle carries two sets of directions, each saying to apply to wet hair, rinse, and repeat if necessary. Method A follows the EU label; Method B is how we would work it in the chair.

Method A: the manufacturer's directions

1. Apply shampoo to wet hair.
2. Massage well and rinse without leaving any residue.
3. Repeat the operation if necessary.

The bottle's original printed directions read: 'With wet hair, apply the Supreme Repair Shampoo until you thoroughly clean the strands. Rinse and repeat the application if necessary.'

Method B: the Brazilian method (salon practice)

Salon practice, not a step printed on the pack.

1. Wet the hair thoroughly with lukewarm water rather than hot: treated hair does not need the heat.
2. Lather at the roots and let the rinse carry the foam through the lengths.
3. Rinse until nothing is left. A second wash only if the first did not clean, as the label allows.
4. Follow with the cream of the same line on the lengths.

Where it fits in the Brazil Protein range

In the Supreme Repair line, this shampoo sits beside the Supreme Repair Moisturizing Cream 250 g, and the two are sold together as the Supreme Repair Home Care Duo. The other home-care lines say on their own fronts who they are for. The Nutrition Power Detox Conditioner reads mixed and oily hair; the Blond Vegan Conditioner reads blond, coloured and grey hair. The Day by Day Shampoo completes the Brazil Protein home care range, and everything is on the Brazil Protein brand page.
