Buying guide
DASHU Fast Change Satch hair dye
The DASHU Fast Change Satch Hair Dye is an at-home colour using naturally derived ingredients. This edit covers the Natural Brown and Black Brown shades and how to get a clean result from each.
What you will find
Two shades of the DASHU Fast Change Satch Hair Dye sit in this edit: Natural Brown and Black Brown. Both are formulated with naturally derived ingredients and built for fast application, which is where the Satch name comes from.
Choosing between Natural Brown and Black Brown
Natural Brown reads warmer and lighter, which suits medium to light base tones or anyone wanting a softer brown. Black Brown sits darker with a cooler edge and gives stronger grey coverage. If you are between the two, the darker shade tends to be more forgiving on regrowth.
How to apply
Start on dry, unwashed hair so natural oils protect the scalp. Section the hair, apply from the roots and work the colour through to the ends, then leave it for the time on the pack before rinsing until the water runs clear. A patch test the day before is worth the small wait.
What naturally derived means here
DASHU markets the Satch line on naturally derived ingredients, meaning a share of the formula comes from plant sources rather than being fully synthetic. It is still a hair dye, so treat it like one: gloves on, good ventilation, and a patch test for sensitivity.
Keeping the colour fresh
Colour fades fastest in the first few washes. A sulphate-free shampoo and cooler rinse water both help the shade last. When roots show, you can spot-apply along the parting rather than redoing the whole head.
