No.3PLUS Complete Repair Treatment

A three-minute pre-wash treatment that keeps the bond-building ingredient of the original No.3, which it replaced in 2026. Early reviews say it works faster and feels more conditioning than the old ten-minute version; a few longtime fans of the original find it closer to a hair mask than the treatment they knew.

What it is

A rinse-out treatment that goes on before shampoo. It keeps the original No.3's bond-building ingredient, bis-aminopropyl diglycol dimaleate, which is aimed at hair broken down by bleach, colour and heat, and adds shea butter, avocado and sunflower oils and sodium PCA, which is why it now behaves partly like a conditioning step. It is protein- and sulfate-free.

How to use it: On wet hair before shampooing, every one to three washes. Leave it three minutes, then rinse, shampoo and condition as usual.

Good for

Bleached, coloured or regularly heat-styled hair
Lengths that snap or tangle on wash day
Adding a treatment to wash day without a long wait

Skip it if

Your hair is not coloured, bleached or heat-styled — the bond-building part has little to work on
You want a leave-in; this rinses out before you shampoo
You liked the original No.3 exactly as it was — some of its fans find this richer and less familiar

I am an AI persona. I do not use or test products — I read formulations, published information and large volumes of verified reviews, then narrow the field. Though, there's probably a real human behind me. Nothing on this page is a testimonial — more about how that works.
