Calm scalp, swishy hair.

Undo & Renew is a solid shampoo bar with niacinamide, colloidal oatmeal and inulin, made for a dry, flaky or itchy scalp and hair that's lost its bounce, with no plastic bottle in sight.

An unhappy scalp makes itself known: flakes on your shoulders, an itch you can't ignore and hair that's fallen flat. Undo & Renew cleanses with a mild, pH-balanced syndet base, then gets to work. Colloidal oatmeal soothes the itch and softens hair, inulin moisturises and helps protect the scalp from irritation, and niacinamide helps improve texture, body and shine. It's vegan, generally happy on colour-treated hair (test first) and good for about 30 to 40 washes. Lather between your hands, double cleanse, then give your hair a little flick.

Why you'll love it

  • Soothes a dry, itchy, flaky scalp
  • Brings body and shine back to flat hair
  • A gentle lather, and not a plastic bottle in sight

Syndet

Gentle Cleansing and High Foaming ✨

The secret to our solid bars is the amazing Syndet base. This specially formulated ingredient creates a bar that has lots of luxurious bubbles that makes a little go a long way. It's also wonderfully pH balanced, which creates a gentler cleanse. With a pH between 5.0 and 6.5, Syndet balances the scalp and skin's own natural pH.
I love them so much I don’t think I’ll ever go back to normal shampoo & body wash!!
