If your hair is still misbehaving in spite of great shampoo, your water might be to blame. Depending on where you live, there could be very hard or very soft water coming out of your tap. Though soft water is gentler, it often makes it tough to wash all of the shampoo and conditioner out of your hair, leaving it limp and lifeless. Hard water, meanwhile, has the opposite affect: It's more efficient, but the harshness can make your hair unhealthy.
I was delighted to discover that both Lush and Robert Craig make specialized shampoos designed for very soft and very hard water. (Robert Craig even offers a free testing strip, so you can find out what kind you have.) Here's a look at the different offerings.
Designed for soft-water areas, the solid Lush Soft Shampoo Bar contains sea salt to give back the body that your hair is lacking because of the soft water. Buy a bar for $7.95 here.
To see the rest,
Robert Craig Shampoo for Soft Water is easy to wash out and designed to prevent limpness; also great for color-treated hair. You can buy a bottle here for $18.
The Lush Hard Shampoo Bar is formulated to remove the calcium residue that often comes with living in a hard-water area. It also costs $7.95, and you can buy it here.
Robert Craig also makes a Shampoo for Hard Water, which contains natural botanicals to purify your locks. Pick up a bottle here, also for $18.
