Overview
Conditioning both the scalp and the lengths, Redken Acidic Grow Full is built for thicker-looking hair. It belongs to a system of shampoo, serum and spray that the brand tested together.
The reason to look is the focus on thicker-looking hair, with a brand consumer test behind it. The limitation is that the test used the whole system of shampoo, conditioner, serum and spray, so the conditioner alone is not shown to deliver that result.
Who it's for
A routine already built around a full system of four products is the situation. Shoppers who plan to use the conditioner by itself, or who need size and directions on the listing, should look elsewhere.
Pros and cons
- Aimed at thicker-looking hair
- Conditions scalp and hair
- Tested within a four-product system
- Test results reflect full system use
- Size and directions not listed
Performance notes
The listing credits thicker-looking hair to a system of four products used together, not to the conditioner alone. Expect the conditioner to contribute conditioning and scalp care rather than carry the whole result. No directions or timeline are given.
