Brazil Protein SOS Protein Fluid (300 ml) is a leave-in fluid marked Professional, with coconut oil on the front and 3rd on its list and hydrolyzed silk 8th. The directions apply it to clean hair strands for 10 minutes, ahead of the mask and the iron. The rinse-out step of the same line is the SOS Protein Mask 500 g.

What the ingredient list shows

The list is a silicone fluid: cyclopentasiloxane 2nd, dimethicone 4th and phenyl trimethicone 5th, with coconut oil 3rd and hydrolyzed silk 8th. That is what gives a leave-in its slip and what the iron works on later. What you control is the evenness of the first layer: comb it through before the mask goes on, and the mask spreads evenly after it.

What to expect

Less frizz, which is the front's own word for it, and an easier finish after the mask and the iron. We judge it on how the strand behaves under the iron, not on the bottle.

Who it is for

• Salon use, as the first step before the SOS mask and the iron
• Frizzy hair: the front prints anti frizz
• Stylists who want a leave-in with silk on its list

Who it is not for

• Clients sensitive to the preservative DMDM Hydantoin, 13th on the list
• Clients who avoid animal-derived ingredients: the silk entry is 8th
• Home use: the front prints Professional

Professional tip

Comb the fluid through before the mask goes on. An even first layer is what lets the mask spread evenly after it, and it is the step we would never rush: a patchy fluid shows as a patchy finish under the iron.

How to use

The EU sticker on the bottle prints the directions in English and Dutch. Method A follows the sticker's legible clauses; the mask step sends you to the mask's own page for its time. Method B is how we would work it in the chair.

Method A: the manufacturer's directions

1. Apply the SOS Fluid to clean hair strands.
2. Leave on for 10 minutes.
3. Then apply the mask of the line, for the time printed on its own pack, and rinse completely.
4. Dry, then pass the flat iron 4 to 5 times per strand. Finish as desired.

Method B: the Brazilian method (salon practice)

Salon practice, not a step printed on the pack.

1. Wash, then towel-dry to damp.
2. Apply the fluid evenly, section by section, and comb it through.
3. Leave it for the time in Method A.
4. Then the SOS Protein Mask, for the time on the mask's own pack.
5. Rinse, dry, and iron each strand the number of passes in Method A, at the setting you use for that client's hair; finish as desired.

Where it fits in the Brazil Protein range

The fluid is the leave-in of the SOS Protein line, and the SOS Protein Mask 500 g is its rinse-out mask. The SOS Protein & Oil Trio puts the two together with the Mix Brazilian Oil 60 ml. It sits under Brazil Protein salon treatments, and everything is on the Brazil Protein brand page.
