ion Sensitive Scalp 20 Volume Creme Developer, Ionic Buffers and Conditioning Protein to Help Scalp Sensitivity, 4 Ounce

I’ve been using the Ion Sensitive Scalp 20 Volume Creme Developer for a while now, and it’s hands down one of the best developers I’ve tried. It’s gentle enough for my sensitive scalp—no burning or irritation—which is a huge plus. The consistency is perfect: creamy and easy to mix with my hair color, giving consistent and vibrant results every time. The 32 oz size lasts me quite a while, making it great value for the price. If you have a sensitive scalp but don’t want to compromise on color performance, this product is definitely worth trying!

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.

This 20 vol developer works great and is very gentle on the scalp. It mixes smoothly with lightener or color and processes evenly without irritation. I also like that it doesn’t have a strong smell. Perfect for sensitive scalps and consistent results. Would definitely buy again.

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!

This developer works really well and is super gentle on the scalp. It doesn’t burn or irritate, and it mixes smoothly with hair color. I got great results and the lift was exactly what I needed. Definitely a good choice if you have a sensitive scalp.

Great product.

This developer is great for sensitive scalps—mild smell, creamy texture, and causes minimal irritation. It lifts hair well when mixed with bleach or color, leaving hair soft. A solid choice if you want good results without scalp discomfort.

I had purchased both the 30 and 20vol developer, I liked this one because it processes hair at a slower rate compared to the 30. I use it to bleach the knots on my wigs, so this is best for lighter wig colors that don’t need much bleaching.
