SCALP CARE

Find the Right Hair Treatment for Your Hair Type

Designed to bring life back to tired strands and stressed-out scalps, these formulas do more than moisturise. They treat, repair, balance and protect - whatever your hair type needs.

Dry or Damaged Hair?

You’ll find everything from ultra-hydrating hair masks to bond-repairing leave-in treatments that tackle split ends and brittleness head-on.

Frizz Driving You Mad?

Tame the fluff with smoothing serums, rich conditioners and anti-frizz treatments that actually work. Each one is designed to soften, seal, and keep humidity at bay.

Dandruff, Oil or Itch?

Give your roots the TLC they deserve with targeted scalp treatments and clarifying scrubs. We've got top-shelf go-tos for soothing irritation and restoring balance.

Coloured or Treated Hair?

Protect your colour with salon-approved products. From toners and purple shampoos for blonde babes to full, colour-safe haircare products, we've got something you'll love.

Hair Falling Flat?

For extra volume, shine or a boost in thickness, explore our full range of hair serums and sprays. They’re lightweight, nourishing and great for heat protection, too!

Why Use a Professional Hair Treatment?

Your everyday shampoo and conditioner can only do so much, and supermarket masks and serums just don’t cut it.

Salon-grade hair treatments are backed by science (and stylists). They’re more concentrated, deliver real results, and help protect the investment you’ve already made in your hair - especially if it’s been coloured, chemically treated or even heat styled.

The right hair serum, mask, or leave-in treatment takes your routine to the next level , delivering targeted care where your hair needs it most. Whether it’s hydration, repair, colour protection or scalp support, there’s a pro formula made for you.

And because we only stock the best in salon haircare, you know you're getting salon-grade results without the salon price tag. All day, every day, right here!

What is the best treatment for dry hair?

Look for hydrating masks or leave-in treatments with nourishing ingredients like argan oil, shea butter, or hyaluronic acid. We love Matrix Food For Soft, Jeval Moisture Ever After, and Pureology Hydrate for giving thirsty strands a proper moisture boost.

Can protein treatments damage hair?

They can - if overused. Protein is great for strengthening weak, damaged hair, but too much can make it brittle. If you’re unsure, balance it out with a moisturising treatment or ask us for a tailored rec.

What’s the best hair treatment for hair loss?

While no product can completely reverse hair loss, the right treatment can help improve scalp condition, reduce breakage, and support stronger, fuller-looking hair. For scalp-focused care, try the Davroe Scalp Remedy, De Lorenzo Tricho, Nioxin Scalp Purifying Exfoliator or Nioxin Hair Booster Serum. To strengthen and thicken hair strands, look to Nioxin Diaboost Thickening Serum or System #1–4 Thickening Treatments - they're amazing!

Does scalp treatment help with hair growth?

Yep! A healthy scalp is essential for healthy hair. Treatments that unclog follicles, balance oil, or soothe irritation can create a better environment for growth. Look for ingredients like salicylic acid, niacinamide, or menthol.

How often should I use a hair mask or treatment?

Once a week is a good starting point for most hair types. If your hair is very dry or damaged, you might use a deep conditioner or leave-in treatment 2–3 times weekly. Just avoid overloading fine hair with heavy products too frequently.
