Dry, brittle hair can be a result of many things, including prolonged sun exposure, hot hair tools, and chemical treatments. Essentially, the culprit is our hair's depleted hydration levels. Our strands are like sponges; they need water in order to function properly, and leaving them parched can lead to hair breakage and cause our little ol' strands to fray easily.

Whatever your hair is going through, hair serums and other hydrating hair products can come to the rescue and bring back life to your 'do. One of the most effective products on the market is Kérastase Nutritive 8H Magic Night Hair Serum, which happens to be on sale for 20 percent off right now during Kérastase's Mother's Day Sale, which goes until May 12 (today) until May 15.

Formulated with humectants like glycerin and niacinamide, the Magic Night Hair Serum (now $47) draws moisture and water back to lifeless strands, reinvigorating dull, stressed hair.

Bain Densité Shampoo — $32.00

Dry strands can be a pain to deal with, but hydrating shampoos can get to the “root” (pun intended) of the problem.

“I LOVE this thickening shampoo! I love everything about it. It’s thick and smells wonderful. It lathers beautifully. My very fine hair looks beautiful and shiny and coupled with the other products in this line have transformed my flat lifeless hair into beautiful, healthy, shiny, and thick hair! I’m 53 and my hair has thinned out dramatically and spent several years using shampoo and conditioner products from companies claiming it will regrow your hair. I finally decided to stop using those and instead use products to thicken and take serums and supplements for growth and I’m so glad I did. Night and day transformation so I’m hooked on this line,” one shopper says.
