Strengthens and repairs hair strands
Aloe vera contains vitamins A, C, and E. All three of these vitamins contribute to cell turnover, promoting healthy cell growth and shiny hair.
Vitamin B12 and folic acid are also contained in aloe vera gel. Both of these components can keep your hair from falling out.
However, there are no studies that confirm conclusively that aloe vera has any benefit in preventing hair loss.
Aloe vera is a popular product that people use on their skin after sun exposure. This is because of its high collagen content and cooling properties. The vitamin content in aloe vera suggests that it might work to repair sun damage to your hair, too.
May promote hair growth
When your scalp has been cleansed and your hair has been conditioned with aloe vera, you might see that hair breakage and loss slows down.
There are plenty of people who claim that aloe vera actually causes hair to grow much faster.
For centuries, aloe vera has been used for its healing properties. It is a plant with thick leaves that contain a gel-like substance. It can be found everywhere, and many people even cultivate their own.
Because it cools and calms the skin when applied, aloe vera gel is sometimes used to treat burns and other skin wounds.
The raw gel of the plant is the most effective form of aloe vera for hair care. This gel can be purchased at almost any pharmacy or extracted from freshly cut leaves taken from a living plant if you have one. The gel is clear in variety and somewhat watery.
Aloe vera can be used to condition and improve dry, damaged hair by rubbing it into your scalp and hair and allowing it to penetrate the follicles. Use a mild shampoo to remove the gel after it has been sitting for an hour.
Aside from using the gel on its own, you can also mix it with your conditioner for a boost of moisture. Additionally, you can use it as a spray using one part aloe and two parts water. This can be especially helpful if your hair is feeling dry.
How should you apply aloe vera?
Once you cut your aloe plant and remove the gel, it can be applied directly to your scalp or hair. But before rushing into it, make sure you’re not sensitive or allergic. To check if you are allergic, it is a good idea to do a test spot on the inside of your arm to see if a reaction develops one to two days before applying it to your scalp.
Note: Many people advise running the fresh aloe gel through a tight-knit strainer before use to avoid small particles in aloe from leaving residue on your hair. Using aloe excessively can also lead to similar effects.
