Kristin Ess The One Signature Shampoo & Conditioner Set, Sulfate-Free, 33.8 fl oz Each with Pumps

A sulfate-free shampoo and conditioner set for anyone who wants one matched pair instead of two separate bottles. Kristin Ess The One Signature Shampoo and The One Signature Conditioner arrive together, each 33.8 fl oz with a pump, colour-safe, vegan and cruelty-free, and formulated for all hair types. The shampoo lists avocado oil and castor oil.

What is in the box

You get one bottle of The One Signature Shampoo and one bottle of The One Signature Conditioner. Each bottle is 33.8 fl oz, so the pair adds up to 67.6 fl oz of product in total, and each one is fitted with a pump instead of a flip cap. That pump matters if you keep big bottles on a shower shelf: you portion product without tipping or squeezing a heavy bottle. If you have been buying a shampoo and a conditioner separately, this set covers both steps at once and keeps the two formulas matched to each other. The shampoo is the clarifying step and the conditioner is the softening step, so the order of use stays simple.

Size and value per bottle

Both bottles are full size at 33.8 fl oz. Reviewers frequently bring up the size and how far a set like this stretches, and many mention the pumps as a practical detail for daily shower use. Buying the pair together is also a way to try the brand at a lower cost per bottle than picking up the two separately. Nothing here is a travelling or sample size, so keep that in mind if you are shopping for a gift or for a single person's routine.

Hair types and colour-treated hair

The set is described as suitable for all hair types, so it is not narrowed to one texture or concern. It is also colour-safe, which means it can sit inside a routine for colour-treated hair alongside whatever else you already use. The shampoo is labelled sulfate-free, and the set carries vegan and cruelty-free flags with sustainable packaging. If you are working out whether a set is sulfate-free, check the label wording on the bottle rather than the bottle shape, because the two are not related.

How the pair feels in use

Reviewers often say the shampoo lathers well and rinses cleanly, and that hair feels soft and easy to detangle once the conditioner is in. A number of them describe the conditioner as lightweight rather than heavy, so it does not sit on the hair. The shampoo is a daily formulae that clarifies without stripping natural oils, and the conditioner is made to weightlessly soften and smooth the parts of the hair natural oils do not reach. Together they aim for hair that looks hydrated, feels soft, looks shinier and has some bounce.

Scent and packaging

The set carries a pear fragrance. Reviewers usually describe it as noticeable while you wash and pleasant, with some saying it lingers lightly on hair afterwards. Both bottles use pumps rather than flip caps, and the packaging is described as sustainable. If scent strength matters to you, note that this is a fragranced set rather than a fragrance-free one, and read the reviews for how people describe the strength after drying.
