## Description

desertcart.co.jp: Sensitive Scalp 20 Volume Creme Developer by Ion : Beauty

Review: I have naturally black hair and this didn’t work. I thought of leaving it for longer then 40min but it’s not recommended in the instructions.
Review: I have used the Ion Sensitive Scalp 20 Volume Developer every time I have recolored or wanted to lighten my hair. I have a very sensitive scalp, and not once in the past 5 years of using this product have I ever had an issue. I have also tried the 30 volume and did not run into any complications. I am a semi-frequent bleacher and typically touch up my roots every 1-2 months when I redo my hair color. Even with semi-frequent bleaching, I have never had any major or scary damage. Compared to other bleaches, this one has a less pungent smell and does not burn my scalp... I would still recommend you open up a window, though. I am naturally a dirty blonde (I would say a level 7/8), so the 20 volume works great for me :). Whether I want a full blonde (such as in the photo) or to touch up my roots when I have colored hair, I always use Ion. Amazing product and my go-to for bleach!

*by E***O on September 2, 2025*

Very good developer, excellent quality. I used it with Ion hair color and it worked perfectly: the mixture was creamy, easy to apply, and didn't run. It doesn't have an overly strong scent and didn't damage my hair like other developers I've tried. The lift level was just as expected with 20 volume and left the color even and shiny. Plus, my hair felt soft after rinsing.
