Biolage Scalp Sync Calming Shampoo (400ml) with Glycolic Acid for Dry or Sensitive Scalps
Product description
What it’s for
Biolage Scalp Sync Calming Shampoo is a scalp-focused wash built for people whose scalp feels dry, tight, or a bit irritable. The idea is pretty straightforward: gently help balance scalp moisture and sebum levels, so you’re not constantly battling itchiness alongside dryness. It’s also described as soothing and refreshing, which matters if your scalp is sensitive rather than just “a little dry”.
This isn’t marketed as a heavy-duty treatment for one-off problems. It sits more in the everyday category: a calming shampoo you can use as part of a routine, especially when your scalp feels reactive.
How it works (on paper)

The shampoo is infused with a tea blend intended to reduce irritation, alongside glycolic acid, which is described as clearing away dead cells. In practice, that combination can appeal if you want two things at once: a calmer scalp feel, and a more “clean sweep” feeling on the scalp surface.
You’ll usually notice the difference through comfort rather than drama. A product like this is aiming for less itching and less dryness over time, not an instant, obvious makeover after one wash.
What you’ll notice in use


To use it, you apply it to wet hair and massage into a lather before rinsing. The routine is easy to slot in—no complicated steps.

A practical micro-scenario: say you’ve just come back from a dry-feeling week (air-con, winter heating, or just a generally sensitised scalp). In the shower, you’d massage this into the scalp for lather, rinse well, then follow with a conditioner from the same Scalp Sync line. The “refresh and soothed” promise is essentially about how the scalp feels once you’re out of the shower and when you go to style the next day.
Where it shines
- If your scalp is dry or sensitive and you want a shampoo that targets itchiness and dryness, this direction makes sense.
- The balance-of-moisture-and-sebum angle is useful when scalp problems come from more than one cause.
- Glycolic acid and a tea blend gives it a more active feel than basic soothing shampoos, without turning it into a medicated product.
You also get a helpful hint about pairing: the base instructions suggest using the Scalp Sync Universal Conditioner afterwards. That’s relevant because scalp-focused shampoos often work best when the rest of your routine doesn’t fight the goal.

Things to consider before buying
It might not be perfect if you’re expecting a deeply moisturising, “no exfoliation” type of wash. The inclusion of glycolic acid suggests it’s doing more than pure comfort—so if your scalp is extremely reactive, it may be worth introducing it gradually.


Also, while it’s positioned for dry or sensitive scalps, that doesn’t automatically mean it’ll suit every single skin type or sensitivity level. Sometimes scalp products need a bit of trial and error, especially if you’re switching from a very gentle shampoo.
Finally, it’s 400ml, which is decent for regular use, but you’ll still want to think about whether you’ll actually keep it in rotation or just use it during flare-ups.

Mini FAQ
Is it meant for dry or sensitive scalps?
Yes—based on the product positioning, it’s designed for dry or sensitive scalps and aims to help reduce itchiness and dryness.
What’s the main benefit you should expect?

A more balanced scalp feel, with reduced irritation and dryness. It’s the comfort outcomes that this is aiming for.


How do you use it?
Apply to wet hair, massage into a lather on the scalp, then rinse. The instructions also recommend following with the Scalp Sync Universal Conditioner.
Does it exfoliate?

It contains glycolic acid, which the description says helps clear away dead cells. So it’s not just soothing—it does some scalp-surface clearing too.
Should you buy it?
If you’re shopping for a calming, scalp-focused shampoo that targets both comfort (itchiness and dryness) and scalp surface build-up (via glycolic acid), Biolage Scalp Sync is a solid contender. It makes sense if your current routine isn’t addressing scalp moisture and sebum balance, or if you’re looking for something you can use regularly—not only when things flare up.
It’s not the best match if you want a purely non-active, ultra-gentle wash with zero exfoliating potential. And if your scalp is very reactive to “active” ingredients, you may want to be cautious and introduce it slowly.
Final verdict
Worth considering if your main goal is a calmer, less dry scalp feel with a routine-friendly shampoo and a recommended conditioner pairing. Skip it if you prefer an ultra-basic gentle cleanser with no active exfoliating step, or if you know your scalp reacts strongly to glycolic acid-type ingredients.
