Nexxus Pro-Mend Hair Collection is a nightmare to split-ends. At first I didn’t believe the claim, but after a few weeks of trying I must say the straggly ends are looking much better. It’s one of those hair care systems that I like and loathe at the same time. I love mixing products, but I think this collection works better when used together. My hair loved the conditioner and overnight treatment, but the shampoo dried my hair out. I didn’t straighten my hair when I used it, but I’m interested to see how my split-ends look after a great blow dry. I usually leave the heat alone in the summer, but you never know.
