Truss Equilibrium Shampoo is built for one specific complaint: an oily scalp paired with dry ends. It is the shampoo for someone who feels like they need two different products for two different parts of their head, in one bottle.

Who this is for

Anyone whose roots get oily within a day or two of washing while their ends stay dry, rough, or prone to static. That combination shows up most in longer hair, fine to medium hair, and hair that gets heavier conditioner on the ends but nothing to manage the scalp. If you have caught yourself using a clarifying shampoo at the roots and a rich conditioner on the ends just to get through the week, this is the shampoo built to replace that workaround.

Who should skip it

If your scalp is dry rather than oily, this is the wrong formula. A balancing shampoo made to control oil will not help a dry, flaky, or tight scalp, and may leave it feeling more stripped.

If your hair is oily everywhere, roots to ends, you do not need the dry-ends half of this formula. A straightforward clarifying or oil-control shampoo will do the job with less complexity.

If your hair is evenly dry with no oil issue at the scalp, look at a straight hydrating shampoo instead. Equilibrium is doing two jobs at once, and if you only have one of those problems, a single purpose formula will usually do it better.

How a stylist uses it

Concentrate it at the scalp, where the oil control actually needs to happen, and let the lather run through the ends on its way out rather than scrubbing the ends directly. The ends do not need the cleansing power, they need to be left alone as much as possible during the wash.

Recommend it to clients who describe their hair as needing a wash more often than they would like, but who complain about dry, frizzy, or static-prone ends between washes. That description is the tell for this product.

How it compares

Against running two separate shampoos, one for the scalp and one for the ends: that approach works, but it means buying and storing two bottles and switching mid-shower. Equilibrium is built to do both jobs from one bottle, at the cost of not being the single strongest option at either job on its own.

Against a straight hydrating shampoo: a hydrating shampoo will do more for the ends but is more likely to leave an oily scalp feeling weighed down faster between washes. The tradeoff is real either way, this formula is aimed at the middle.

What to expect

A scalp that stays comfortable longer between washes, and ends that are not fighting the shampoo the way they would with a straight clarifying formula. It will not fully solve an oily scalp on its own if diet, hormones, or product buildup are driving the oil, and it will not repair dry, damaged ends, it manages them during the wash.

The honest tradeoff of a dual-purpose formula is that it is a compromise by design. It will not out perform a dedicated clarifying shampoo on oil control, and it will not out perform a dedicated hydrating shampoo on moisture. What it does is remove the need to choose between the two.

Size and value

Truss sells this in one size, 10.14oz, at $33.60. That works out to about $3.31 an ounce. There is no size decision to make here, it is a single bottle at a single price, which keeps the buying choice simple for a client who just needs the one product.
