"You better get you some!! I purchased the milk serum because the texture of my hair was severely dry and brittle due to an autoimmune, menopause, and extended styling damage. I used it once and noticed results immediately. I am continuing to use it and the results keep getting better. I received a sample of their foundation collection shampoo/ conditioner and loved the results so much, I ordered the full size."
"Great product. As I’ve gotten older , my curly hair has finer and I have a lot less hair 😞. Now in my 50’s, have been searching for products that dont weigh my hair down , that allow for a nice frizz free definition of curls. Thia product is great. Now just one step , previously used leave in conditioner plus curl cream. doesnt leave hair crunchy or wet looking. Light fragrance. Great for air drying. Havent teied to diffuse. Is a bit costly .. and have to use a bit more product. But overall a great product. Wouls love if a travel Size was available"
"I was bombarded by the ads for this product and finally caved in and purchased. Glad I did! I've been using it for about two weeks now and have noticed a difference in how it holds my waves. My hair is on the finer side and has a natural wave. This product is light weight, smells great and gives my strands what they need to maximize on their texture. I use it before the styling foam and together, they are *chefs kiss!*"
"It’s been a long time since I’ve really been happy with an internet purchase. It’s usually hype driven. But i decided to try it because the texture of my hair has changed since i turned 60 ish. I really am enjoying the softer feel, the nice scent, and how much better my hair looks and feels. I’m glad i tried Roz. I’ll most certainly be ordering again,"
"I purchased the shampoo, condition and milk hair serum. I really enjoy the fragrance, it is a nice but not-overpowering femine note. I have very fine hair and super hard water, which don't always mesh well. My hair is noticeably smoother and more manageable. The milk hair serum is a real super star containing frizz!!"
"My hair is very fine and wavy. This milk serum does an amazing job letting my hair flaunt its natural waves when applied to towel damped hair, but keeps it beautiful the next day smoothing fly aways! My hair doesn't look oily the 2nd day after, which is so hard to find from other brands. For these reasons, I would recommend this. The smell is sweet and slightly floral, and lasts for a short time."
"I cant get over how much I love the Roz Hair Milk! Ive been struggling with hair loss so as part of my new regime, ive stopped using conditioner and replaced it with ROZ. My hair is so soft and shiny and smells like literal heaven. Highly recommend!"
"I like it because it feel smooth and doesn’t make my hair crunchy very natural beautiful look"
"Love the serum. Helps my type 4 dense coily hair feel so soft wet or dry. The serum helps detangle as well. The greatest challenge due to the density of my hair, I need to use more than what others might use and will go through the bottle faster which can be costly."
"I try to be pretty low maintenance with my hair, even so, it still needs something. I’ve found that with the Hair Milk Serum, I can be less particular about mousses and gels because the serum tones down some of the frizz when diffusing. I’d say the main drawback for the product is the scent. I like the smell, but it’s a bit too strong and long lasting. Fortunately, when following up with mousse or gel, the scent seems to reduce a little."
