Definitely recommend for processed hair

Was gonna wait to try this a few more times before reviewing, but was so impressed and exceeded my expectations that I’m compelled to review it now lol. My hair is less than 50% bleached from ombré process months ago, was doing pretty well with bond treatments and purple toning products regularly until last month or so. Finally caved and got this in the mini size to try first. Wow. I did overdo my first wash with more than the initial 3 pumps recommended, but my hair already feels noticeably different after first use. I’ll def invest in the bigger size soon. Even the mini could last a while if I just use 3 pumps or less each wash, and I only wash 2x or less a week.

Must try.

So worth it. In three washes my hair was softer my curls were more defined and it has a nice scent to it. I will definitely be repurchasing forever
