Fine, flat hair has a real talent for doing the least — lying down by 11am and calling it a lifestyle. This lightweight cleanse from Redken steps in right at the source, giving limp strands a fresh, scalp-balanced start instead of a shrug.
TL;DR: A lightweight densifying shampoo from Redken, built for thin, flat and fine hair. It cleanses gently without stripping, rebalances the scalp's pH with azelaic acid, and preps limp lengths to look fuller and thicker. It's the first step in the Acidic Grow Full System, it's vegan, and it's safe for colour-treated hair.
Product Details and Benefits
- Gentle, non-stripping cleanse: Lifts away oil, product and daily build-up while leaving the scalp's protective barrier intact — clean hair, no tight, squeaky, over-washed feeling.
- Rebalances scalp pH with azelaic acid: Azelaic acid helps restore the scalp mantle's naturally acidic pH, creating a healthier-feeling foundation for fuller-looking hair.
- Caffeine to wake the scalp up: A caffeine kick energises and awakens the scalp right at the root.
- Prebiotics for scalp comfort: Prebiotics help moisturise the scalp's acid mantle, so cleansing never leaves things dry or tight.
- Made for fine, thin and flat hair: Lightweight enough to cleanse thoroughly without weighing strands down or flattening them further — density starts at the wash.
- Kind to colour: Suitable for all colour-treated hair, so your salon shade stays exactly where you left it.
- Vegan formula: No animal-derived ingredients or by-products, and never tested on animals.
- Warm citrus fragrance: A salty-citrus scent that opens on Italian lemon, settles into neroli, and finishes on vanilla bean.
How to Use
- Wet hair thoroughly — lukewarm, not lava.
- Massage a coin-sized amount into the scalp and roots, working up a light lather.
- Rinse until the water runs clear.
- Follow with the Redken Acidic Grow Full System Densifying Conditioner — and, for the full effect, the Scalp & Hair Serum and Instant Densifying Spray.
Pro tip: Fine hair goes flat at the roots first, so keep the lather concentrated on the scalp and let the suds rinse down through the lengths on their own. The mid-lengths get all the cleansing they need without the extra weight that drags volume back down.
Why You'll Love It
If your hair's idea of "volume" is a brief and tragic memory, this is the reset it's been waiting for. Give thin, flat strands a cleaner, better-balanced starting line — add the Redken Acidic Grow Full System Densifying Shampoo to your cart and let the fuller-looking days begin.
