Relief for a Dry, Itchy Scalp
Normally, I don't oil my scalp. However, there are times (like now, during the winter) when I experience dryness at the scalp. Hollywood Beauty carries a great line of hair oils that easily absorb into the scalp, quickly eliminating any white, patchy areas. The best thing about them is that they're so lightweight, they won't weigh the hair down. You can purchase them at Long's Drugs and or your local beauty supply store.

If you're suffering from a dry, itchy scalp, then perhaps you can benefit from a deep conditioning treatment. Organic Root Stimulator has a great, moisturizing deep conditioner that adds moisture to dry, brittle hair, while soothing a dry scalp.
If dandruff seems to be a recurring issue, you may need to switch over to a medicated shampoo such as T-Gel. I would also recommend consulting with a professional about your condition.
