What is It?

An essential at the tinting step of your treatments, our vegan-friendly BrowStay 3% Developer works in conjunction with the BrowStay Hybrid Dyes to create a long-lasting, bespoke colour for all of your clients.

BrowStay 3% Developer activates the colour molecules in our BrowStay Hybrid Dyes by opening the cuticle layer of the brow hairs. This allows the dye molecules to penetrate deep into the hair cortex for that intense colour.

100ml (enough for up to 500 treatments)

Why you'll love it

Our BrowStay 3% Developer has a creamy formula that mixes effortlessly with the BrowStay Hybrid Dyes for a consistency that is easy to work with.

The product contains 3% peroxide, the ideal percentage to work with the hybrid dye formulas. It’s also infused with coconut oil and pro-vitamin B5 to help hydrate, nourish and lock in moisture during treatments.

All this, housed in a 100% recyclable bottle.
