3/55$ - New - Keratin Hair Treatment Kit

I've used this keratin kit before, and it worked well for my hair. Since I haven't had the chance to use this one, the kit is new, although the box shows some minor edge damage, as depicted in the photos. For reference, my hair type is 2A. The last photo provides an Amazon reference for a single 120ml keratin treatment solution, which may be helpful for price comparison, as this kit also includes pre- and post-treatment care products (4*120 ml).
