Synopsis
Source of validity: Scientific
Rating (out of 5): 2
Jojoba oil has been used traditionally as a hair care ingredient, but there is also some scientific rationale for its use in supporting the hair and scalp. Jojoba oil is unique in that its chemical structure closely resembles human sebum, the natural oil produced by the scalp. This similarity allows jojoba oil to help moisturize the scalp and hair without disrupting the natural balance. Some laboratory studies have shown that jojoba oil can moisturize the skin and has mild anti-inflammatory properties, which may help soothe dry or irritated scalp conditions. However, direct evidence from clinical trials in humans demonstrating that jojoba oil significantly improves hair growth or overall hair health is limited. Most claims about its effectiveness for hair are based on its emollient properties and anecdotal reports of improved hair manageability, shine, and reduced breakage. Overall, while jojoba oil is widely used in hair products and has a plausible scientific basis for moisturizing and protecting the hair and scalp, robust clinical research supporting major benefits such as hair regrowth or prevention of hair loss is lacking. Therefore, the scientific evidence supporting jojoba oil for general hair health is moderate but not strong.
