Aloe vera has been used for centuries as both a medicinal plant and cosmetic ingredient. While you might know it best for soothing sunburns, research shows this succulent plant may also offer significant benefits for hair and scalp health.
In this article, we’ll explore what science tells us about aloe vera’s effects on hair health and how to use it in a hair care routine.

How Aloe Vera Promotes Hair Growth
Research suggests aloe vera may help stimulate new hair growth in several ways.
Aloe appears to influence important biological processes involved in hair follicle development. A study on a hair health supplement containing aloe and other natural ingredients found that it significantly promoted hair growth by activating a process called the FGF pathway. This pathway plays a crucial role in how hair follicles develop (1).
Additional research showed that Aloe perryi extract demonstrated significant wound-healing properties along with promoting visible hair growth. When compared to control groups (animals not receiving the treatment), researchers observed complete skin healing in treated areas (2).
Benefits of Aloe Vera for Hair
Now let’s look at the potential benefits of aloe vera for hair based on scientific research.
1. Soothes Itchy Scalp and Reduces Dandruff
If you struggle with dandruff or seborrheic dermatitis (a common scalp condition that causes flaking), aloe vera might provide relief.
A carefully controlled clinical trial found that aloe vera reduced scaliness, itching, and the number of affected areas in people with seborrheic dermatitis (3).
A comprehensive review identified aloe vera as an effective plant-based remedy for dandruff. The research found that aloe demonstrated anti-dandruff activity by stopping the growth of microbes (tiny organisms) associated with dandruff formation (4).
2. Cleanses and Conditions Hair
Research shows that aloe vera can be an effective ingredient in hair washing products. A study found that hair washing formulations with higher proportions of aloe gel (96.4-96.6%) had better foam stability, conditioning performance, and other positive characteristics compared to commercial shampoos (5).
These aloe-based formulations demonstrated better cleaning ability while maintaining hair moisture, suggesting aloe might help clean hair without stripping away natural oils.
3. Reduces Inflammation for Better Scalp Health
A healthy scalp is essential for healthy hair growth. Research on aloe vera fermentation (a process where aloe is broken down by beneficial microorganisms) found it significantly reduced pro-inflammatory factors (substances that increase inflammation) while enhancing anti-inflammatory factors (substances that decrease inflammation) (6).
This anti-inflammatory action may help calm irritated scalps and create a healthier environment for hair growth.
4. Promotes Hair Follicle Regeneration
Research found that a special gel framework (called a nanoscaffold) containing aloe vera combined with stem cells or their secretions helped improve wound healing while increasing the number of sebaceous glands (oil-producing glands in the skin) and hair follicles compared to control treatments (7).
While this research was focused on wound healing, it suggests aloe may support the structures necessary for healthy hair growth.
What Makes Aloe Vera Good for Hair?
Aloe vera contains several beneficial compounds that may support hair health:
- Vitamins A, C, and E: These vitamins support cell turnover and may promote healthy hair growth
- Fatty acids: Provide anti-inflammatory benefits that can help soothe scalp conditions
- Natural cleansing compounds: Aloe contains substances like saponins and various fatty acids (including capric acid, lauric acid, myristic acid, palmitic acid, linoleic acid, stearic acid, and phytol) that contribute to its cleansing and conditioning properties (5)
Can Aloe Vera Help With Hair Loss?
While more research is needed, there are some promising findings about aloe’s potential for hair loss management.
A thorough review of treatments for pediatric alopecia areata (an autoimmune hair loss condition) assessed aloe vera among several interventions. Though topical corticosteroids (anti-inflammatory medications applied to the skin) and certain immunotherapies showed the highest level of evidence, aloe was included among the alternative treatment options evaluated (8).
More promising results came from research on aloe ferox gel combined with finasteride (a medication used for hair loss) and oregano oil. The study found that this combination enhanced drug delivery through the skin, potentially improving treatment of hair loss (9).
How to Use Aloe Vera for Hair
Based on traditional uses and modern research, here are practical ways to incorporate aloe vera into a hair care routine:
Pure Aloe Vera Gel Treatment
- Extract fresh gel from an aloe vera leaf or use pure store-bought gel
- Apply directly to the scalp and hair, massaging gently
- Leave on for 30-60 minutes
- Rinse with mild shampoo
Aloe Vera Hair Mask
For enhanced benefits, aloe vera can be combined with other natural ingredients. Research shows combination treatments often provide better results than single ingredients alone (9).
Try mixing 3 tablespoons of aloe vera gel with 1 tablespoon of coconut oil or honey. Apply to hair, leave for 30 minutes, then wash out.
Potential Risks and Precautions
While aloe vera is generally considered safe for most people, there are some important considerations:
- Allergic reactions: Some people may be allergic to aloe vera. Always do a patch test before applying to the scalp.
- Quality matters: Use pure, high-quality aloe vera products. Commercial products with many additives may cause irritation.
- Medical interactions: Be cautious when using aloe alongside topical medications, as aloe may alter how the skin absorbs other substances.
A comprehensive review of aloe vera’s clinical effectiveness noted that while it might be effective for certain conditions, there are major limitations to these findings, and researchers haven’t yet fully determined how well it works for different uses (10).
Conclusion
Scientific research suggests several potential benefits of aloe vera for hair and scalp health:
The quality of evidence varies, with some benefits having stronger support than others. Many positive findings come from studies using aloe in combination with other ingredients rather than alone.
Aloe vera is easily accessible, relatively low-risk, and may provide noticeable benefits for hair when used consistently. Since individual results vary, you might need to experiment to find the best way to incorporate it into your hair care routine.
Overall, current research indicates aloe vera shows promise as a natural ingredient for supporting hair and scalp health, particularly for issues like dandruff and scalp inflammation.
