Brazil Protein Day by Day Home Care Duo is a beauty as well set of two Brazil Protein products: the Day by Day Shampoo 500 ml and the Day by Day Conditioner 500 ml. Both are the larger bottle of their line, and both fronts name linseed oil, which is on each list. The shampoo is the wash, the conditioner the rinse-out step, and each keeps its own directions.

Why these together

Each member has one job, in its own words. The shampoo is the wash: apply to wet hair, massage well, rinse without residue, repeat if necessary. The conditioner is the rinse-out step; its directions say after washing your hair with shampoo, apply, wait a few minutes, rinse, or use it to detangle. The set is the backbar pair: two bottles that last, for the basin that sees every client of the week.

What to expect

From the shampoo: hair that rinses clean, with no residue, as its own directions put it. From the conditioner: lengths that detangle while it is in and feel softer after the rinse. Neither front prints a hair type or a result beyond that, and the page does not add one.

Who it is for

• The basin: both bottles are the backbar size of their line
• The client who wants one plain wash and one plain conditioner, with no line claim to explain
• Hair that tangles after washing, where the conditioner's detangling step is the point

Who it is not for

• The shampoo: clients who avoid sulfate surfactants (sodium laureth sulfate is 2nd on its list) or are sensitive to the MCI/MI pair (13th) or to fragrance (7th)
• The conditioner: clients sensitive to hexyl cinnamal, declared last on its list, or to fragrance, 12th; anyone wanting a leave-in, since the directions say rinse

Professional tip

Lather at the root, conditioner off it. The shampoo cleans where the oil sits and the rinse carries it down the lengths; the conditioner goes from mid-length to the ends and never near the root on fine hair. That placement is most of what clients get wrong at home, and it is the one thing we would print on the bottle if we could.

How to use

Method A is each member's own printed directions, under its name. Method B is how we would work each one at the basin.

Method A: the shampoo, as printed

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

Method A: the conditioner, as printed

1. After washing your hair with shampoo, apply the conditioner.
2. Wait a few minutes and rinse.
3. If you prefer, use it to detangle your hair, rinse thoroughly and style as usual.

Method B: the shampoo, the Brazilian method (salon practice)

Salon practice, not a step printed on the pack.

1. Wet the hair thoroughly.
2. Massage into the roots gently, fingertips not nails.
3. Rinse until nothing is left; wash again if the hair is not yet clean.
4. Follow with the Day by Day Conditioner: the pack itself sends you there.

Method B: the conditioner, the Brazilian method (salon practice)

Salon practice, not a step printed on the pack.

1. After the shampoo, squeeze the water out of the lengths so the conditioner is not diluted.
2. Mid-lengths and ends first; little or none at the root.
3. Leave it for the few minutes of Method A.
4. Detangle while it is in, with a wide-tooth comb, from the ends upward.
5. Rinse thoroughly and style as usual.

Where it fits in the Brazil Protein range

The two are also sold as singles: the Day by Day Shampoo 500 ml and the Day by Day Conditioner 500 ml. The other home-care duos are the Supreme Repair Home Care Duo and Nutrition Power Home Care Duo, and the Blond Vegan Home Care Duo and Bio Lamination Home Care Duo. Everything is on the Brazil Protein brand page and under Brazil Protein value sets.
