PRO EXCLUSIVE: ORIGINAL BOND BUILDING KIT

I've bleached my hair twice this year and the bonds feel noticeably stronger after three weekly treatments. The dropper makes it easy to mix just the right amount, and my ends aren't snapping off like they used to.

My hairdresser has been using this on my bleached hair for months, and the difference in how my strands feel during a blowout is honestly night and day. The bond-building technology actually holds up between salon visits, too.

I was skeptical about another bond treatment, but after three washes my color-treated ends feel noticeably less straw-like and hold their shape better. The kit's two-step process is a bit fiddly on a busy morning, but the strengthening effect on my fine hair has been worth the extra ten minutes.
