You don't often hear about cult classic shampoos, but Living Proof's Perfect Hair Day (PhD to those in the know) makes the list. It's safe for all hair types, affordable and gentle enough to use daily.

You can't age out of protecting your hair. With more women choosing to keep their hair a natural gray -- and the trendier among us dyeing it silver before it has a chance to get there -- it's no surprise that a brand created a shampoo specifically for silver hair. This formula softens the coarseness that can come with aging hair and neutralizes yellow tones, leaving you with pure silver hair.

A major curl challenge is taming your locks without weighing them down. This formula ditches the sulfates, parabens, silicones and dye that can cause build-up, and includes rich mango butter and Tahitian gardenia. You'll smell like a garden, and we mean that as a compliment.

The last thing you need when hair is already dry and brittle is a harsh cleanser to further wipe out all your hair's natural oils. This repairing sulfate-free shampoo is made with moringa tree oil and hyaluronic acid (it works on your hair and your skin!) to naturally add moisture to dry hair.

This isn't the 2-in-1 product you remember from childhood. Acure's joint shampoo and sulfate-free conditioner is paraben-, sulfate- and cruelty-free, in addition to being vegan. You'll be skimping on time, not luxury.
