Peroxide (in brown bottle) vs. sun-in???

Question

which will make hair more lighter.

or is it the same?

also:

is the lemon juice sun-in work better than original. cause i have both!

Answer 1

mix your own peroxide and lemon juice apply before you sun !

Answer 2

It's all about the peroxide volume.

Standard household peroxide is 3%.

Having difficulties on finding info on SunIn, but I'm going to guess it's a little higher.

Developers (peroxide) sold at beautician stores like Sally Beauty are much higher volume,pretty inexpensive, and quicker.  They are sold in creme and liquid form. 20 Volume is around the low range.
