How Often to Use Bond Treatments, and How to Layer Them with Protein and Moisture

Suits

Damaged looking hair of any type that needs one proven weekly treatment step: bleached, coloured or heat styled hair that feels fragile and breaks easily in brushing.

Skip if

Your hair is healthy, unprocessed and only dry. No.3 is a treatment, not a conditioner or a moisture mask, and the brand says so on its own listing; dry hair without damage is better served by the No.8 mask in this edit.

Suits

Bleached, coloured, chemically serviced or heat styled hair that looks and feels damaged, for owners who want the treatment step finished in four minutes with no rinse and no conditioner.

Skip if

Your main complaint is dryness rather than damage, or you want a rich mask ritual. This is a light cream dosed in single pumps, and the moisture brief belongs to the No.8 or Amika entries here.

Suits

Processed hair that is washed and heat styled often: owners who want the bond step to live in their daily styling routine instead of a weekly pre-shampoo appointment.

Skip if

You want the strongest single treatment in the Redken line. That is the Intensive Treatment bottle in this edit, at a 14 percent bonding care complex against this tube's 5 percent conditioning care complex, and the two are not substitutes.

Suits

Hair running a bond treatment that still feels dry: this is the conditioning partner step, published for smoothness, body and shine across all hair types, in a clean dosing pump.

Skip if

You want a bond treatment itself. No.8 carries the line's technology naming inside a moisture formula, but its published job is moisturising; the treatment heavy lifting in this edit belongs to No.3, No.0 and K18.
