There's more than one good reason why Cleopatra demanded goat's milk baths and, by extension, why you should wash your hair with it. For those of us who don't live near a petting zoo, Nutra-Lift makes a shampoo, called Simply Superb, with organic, non-pasteurized goat milk ($18 for 8 oz).

Goat's milk is a very good source of the amino acid tryptophan. In fact, a cup provides 35% of your required daily intake. Tryptophan is one of the amino acids in hair, but is easily destroyed by UV light and therefore a decrease in it is a recognised indicator of hair damage.

Goat’s milk is a good source of that other healthy hair vital, calcium, and it contains capric and caprilic acids which balance skins alkalinity and help prevent it from being “stripped” of natural moisture.

Nutra-Lift Simply Superb Shampoo doesn't have the heavy anti-oxidant guns of its Healthy Hair and Healthy Scalp Shampoo (one of our Five Best shampoo picks), but has a similar blend of organic botanicals with pomegranate and green tea. Pine cone extract is an immune system booster and antioxidant. Proteins in hops are said to repair damaged hair, which is why washing your hair with beer isn't such a crazy idea. Silk amino acids, or hydrolized silk, dry to form a transparent, crystalline protective film that seals the hair.
