Aloe vera plants contain a thick sap that offers deep conditioning benefits. Because of this, this gel is a good natural conditioning agent for hair. The book "Naturally Healthy Hair" points out that aloe vera gel also has antibacterial properties that can treat scalp issues such as dandruff. Aloe vera is generally quite mild, but you may want to test a small amount on your scalp before doing a full treatment. Allergic reactions are rare, but can happen with very sensitive skin.
