Looking for an inexpensive way to improve your hair growth and reduce graying? Consider PABA, a compound found in milk, eggs, grains, and meat. PABA has been used to improve discoloration in skin and hair, ease digestion, and even increase fertility in women. It can be taken as a pill, powder, or extract, and daily doses ranging from 200 mg to 24 grams have been shown to help hair darkening and return gray hair to its original color. PABA is also necessary for the synthesis of folic acid in our body and deficiency may manifest as fatigue, irritability, depression, and constipation, as well as weeping eczema and patchy skin. To get your PABA fix, try incorporating rice, eggs, molasses, wheat germ, and brewer's yeast into your diet. And if you're considering a PABA supplement, be sure to protect it from heat and sunlight during delivery to avoid melting or damage.
