Absolute Collagen Thickening Shampoo and Conditioner Set, 500 ml

Absolute Collagen’s Thickening Shampoo and Conditioner Set pairs two liquid hair-care products aimed at fine, thin or thinning hair. The listing claims up to 20% thicker hair in eight weeks when used together five times a week, but this is a manufacturer-reported result, not a guarantee for every user.

What to know before buying

Listing details to confirm

The up-to-20% thickening claim is based on the listing's stated trial and use conditions. It should be treated as a manufacturer claim, not a guaranteed outcome. The title names 500 ml, while another listing feature states 2 x 250ml, so confirm the pack-size interpretation before purchase.

Who is it for?

A good fit for

People with fine, thin or thinning hair looking for a shampoo-and-conditioner pair with claimed volumising and thickening benefits.
Buyers seeking paraben-free and SLS-free hair care, including those with coloured hair, for which the listing claims colour-safe use.

Less suited to

People seeking a low-frequency wash routine if they want to follow the maker's stated five-times-weekly optimum-use guidance.

Customer feedback highlights perceived effectiveness, a small amount needed per application, and hair described as softer and shinier, with reports of reduced hair loss or frizz and improved volume and texture. These are customer impressions, distinct from the listing's separate thickening claims. Value opinions are mixed, so buyers should weigh the set's routine and price against their preferences. The aggregate rating is generally positive, but it does not establish how the set will perform for a particular hair type.

Positive themes

Customers describe softer, shinier-feeling hair and report that a small amount is enough for application.
Feedback includes reports of reduced hair loss or frizz and improved volume or texture.

Frequently asked questions

What comes in this set?

The listing describes a shampoo and conditioner set with two items. It also states 2 x 250ml in a feature, while the title gives 500ml for the set, so check the selected listing for the exact size presentation.

How often does the maker recommend using it?

The listing recommends using the shampoo and conditioner together five times a week for optimum results. It also says every other day may suit some routines, though results may take longer.

Does the listing guarantee thicker hair?

No. It reports an up-to-20% result in eight weeks under stated use conditions, but this is a manufacturer claim and not a guaranteed outcome for an individual.

Is it presented as suitable for coloured hair?

Yes. The listing describes the cleansers as colour-safe and suitable for coloured hair. This is a product claim, not an independent assessment.
