  • Lovemonger1 - Highly Recommended

    I use this twice a year to prevent mold growth in my shower and it works great. Just sprayed on, let it sit overnight, then with a very lightly moistened sponge go over the job to get rid of all the residue drips and spotting marks. Love this product.

  • Atswei - Perfect for my natural hair!!!

    I don't usually write reviews but I feel I should put this out here especially for my fellow naturalistas. I am a natural, with the 4b/4c type of hair and I know how difficult it is to manage natural hair (especially the 4b/4c type). I decided to go natural last year because I saw a friend's natural hair and I loved it. I did my big chop and was very excited..Unfortunately the products that worked for my friend did not work for me and I was stuck. I have (or rather had..thanks to cantu..hehehe) very coarse hair..it was always brittle, dull, dry and kinda stuck inside(was kind of growing inside). I hated this. I tried lots of products but they never worked..my hair was still the same; dry, brittle, dull and and very coarse. I read blogs on natural hair care and tips but I still could not get anything meaningful..It was difficult to get the right products for my afro. I considered texturizing the hair..I read about it and I was discouraged. I was on the verge of going back to perm when a friend told me to change my hair regimen..she said to do lots of deep conditioning (with egg yolk, honey, some conditioners, pure virgin olive oil, tea tree oil etc..) and use Cantu products. I was a bit skeptical since I had tried several products that didn't work..but I decided to give this a try. So I came on Amazon to search for some cantu products. I got the cantu shea butter shampoo cream, the cantu shea butter leave in repair conditioning cream and the cantu shea butter grow strong treatment. Soon as my products arrived, I did a shampoo wash.. I couldn't believe it.. the shampoo worked magic for my hair.. it freed the knots in my hair and I was able to comb as if I had conditioned it. I could actually feel my scalp breathing.. The grow strong and leave in repair creams made my hair really soft and manageable. I could comb my hair with no pain. (I know these two kind of leave residue.. but my trick is I rub a little olive oil in my palms and massage it through my hair and that takes care of it). The products kinda freed my hair..its now soft, has no knots, easy to comb or twist, looks and feels well moisturized and I can see the curls/coils are kinda defined now. The hair stretches too.. I can really see the length of my hair now and oh my gosh..I am so in love with it! I love my cantu products..now that I have FINALLY FOUND products that work for me(*whew*), I will religiously follow my daily hair regimen and I know in a month or two I am gonna be even more head over heels with my natural hair! Thanks Cantu...You guys rock!!!

  • Jackie Perl - I simply can not say enough good things about this hair mask

    I simply can not say enough good things about this hair mask. I have very long and thick hair that has become very difficult to manage at times, and I have been looking for a solution that will help keep it manageable and also help to repair some of the damage that has been done to my hair as I have colored it multiple times and used a lot of curling irons and straightening irons on it over the years. This hair mask is the perfect solution. I am a graduate student who is most definitely balling on a budget, but this hair mask is so affordable because you only need to use it one time per week so it is definitely going to last you a very long time. It smells absolutely amazing and you really start to notice real changes in your hair after just one use. The bottle design is cool and young and I must admit that may have been what originally drew me to this product, however I have continued to use it because of how well it works and how amazing it has made my hair look. I am definitely very satisfied with my purchase and I am definitely going to be a long time purchaser of this product. Keeva Organics is definitely a brand that I know and trust because they make high quality products such as this one. I would definitely recommend this product very highly to any one who is looking to totally transform the appearance of their hair. I received this product at a discounted rate in exchange for my open and honest review.
