Which is a more gentle developer for hair- 20 volume or 30 volume?
Volume 20 developer is definitely more gentle and the ideal choice for most of them who wish to bleach their hair before the coloring process.
2.Oh! Lightning Kit has a very high performing bleach powder, so using our gentle 20 volume developer should give you a raise of up to 3-5 levels.
Use bleach with a 30 volume developer for lifts of more than 4 levels.
If you are planning to bleach your hair for the 2nd time, we absolutely recommend you using a 20 volume developer only.
Even for the roots, make sure you use 20 volume developers only as it’s more gentle.
