For some people, shea butter is not an effective moisturizer (or sealant). In order to enhance its moisturizing properties, oils (e.g., olive oil), aloe vera gel, or other substances are added and the final mixture is applied to damp (not dry) hair. However, even this technique does not work for some. So now what?

Honey is a natural humectant, or substance that aids in moisture retention. Adding 1-3 teaspoons of honey to a cup of shea butter may do the trick. However, if this option does not work, try ...
Alternative - Glycerin and Water
Vegetable glycerin, like honey, is a natural humectant. Mix a teaspoon of vegetable glycerin with a cup of water to start. Spritz on damp or dry hair. Add more glycerin to your mixture if desired.
Alternative - Products Containing Propylene Glycol
Propylene Glycol is yet another humectant. If you are familiar with jerri curls and leisure curls, then you are aware of the wet drippy look of these styles. Well, this "wet drippy" look is achieved by products called activators, which usually contain propylene glycol as well as water and glycerin. Activators can be applied to all hairs, natural or relaxed, to aid with moisture retention. (Propylene glycol in this form is safe.)
Alternative - Kokum Butter and Honey
Alternative - Kokum Butter and Honey
Kokum butter is stocked with fatty acids (e.g., oleic acid, stearic acid, etc.). It is used in certain natural hair care products to aid in moisturization. It is also very firm. Try mixing kokum with another butter, such as mango or avocado, to make it usable. Add some honey to improve moisture retention.
