Aloe vera is a plant that grows in tropical and sub-tropical areas of the world. People appreciate it for its decorative uses and medicinal properties.
People have valued this member of the Liliaceae family for its many healing and regenerative properties for millennia.
Advocates of using aloe vera for hair health point to its plentiful supply of vitamins, minerals, and other ingredients linked to hair growth. They say these properties are signs of its ability to promote healthy and abundant hair.
The connection between the properties of aloe vera and hair vitality has not, as yet, been proven by scientific research.
Here, we will explore the subject more, along with looking at other benefits of aloe vera for the hair and scalp.
-
One of the earliest written mention of aloe vera's curative effects dates to 2100 BCE.
-
Aloe vera's many uses may be partially explained by its makeup. It contains 75 active ingredients, including vitamins A, C, E, B12, and choline.
- Some nutrients have a marked effect on hair quality, and nutritional deficiencies can lead to hair loss.
- Research suggests a positive correlation between aloe vera use and hair health, but no firm scientific link has been made.
According to the Trichological Society, an independent association for professionals involved in the study and treatment of the human scalp and hair, the average rate of hair growth is 1 centimeter per month.
Shampoos and other hair products have not been shown to have a significant impact on this rate, which is primarily determined by genetics and an individual's health.
Aloe vera is thought to work chiefly because of its contents, which include:
- vitamins
- essential amino acids
-
minerals, such as copper and zinc, which are important for hair growth
- plant steroids
- fatty acids
Aloe vera is big business. In 2004, cosmetic, food, and pharmaceutical products containing aloe vera were a $110 billion-a-year industry.
Aloe vera is a natural product and carries few risks so people can try it safely despite the lack of scientific consensus.
Research analyzing the healing properties of aloe vera has generated the following:
- a potential link between aloe vera and improved healing from burns
- aloe vera may work as a laxative, but the safety of this has not been tested
- encouraging early signs of aloe vera's usefulness in treating diabetes
People have used aloe vera for centuries to address a multitude of health problems, but although these remedies are well-established in folk wisdom and popular culture, the majority of claims have not been subjected to scientific review and study.
Aloe vera's use in the treatment of seborrheic dermatitis is one of its claimed benefit for hair care that has been studied.
Seborrheic dermatitis (SD) is a skin disease that causes a pinkish-red rash and crusty, yellow-white scales on the surface of the skin, which may also be swollen and greasy. SD frequently develops on the face and scalp. When infants develop SD on their scalps, it is called cradle cap.
One study found that treatment with aloe vera resulted in a significant reduction in itchiness, scaliness, and the size of the area affected by SD. Since SD can, in some cases, lead to temporary hair loss, this is one clear use of aloe vera for hair growth.
Also, there is speculation that since aloe vera contributes to a healthy scalp, which is important for healthy hair growth, this bolsters arguments about aloe vera's effectiveness in hair care.
Researchers have suggested that the benefits of aloe vera for hair may be due, at least in part, to its ability to stimulate blood circulation and improve delivery of oxygen and nutrition to hair follicles.
Are there any risks?
The external use of aloe vera usually does not have undesirable side effects. However, cases of the following have been reported:
-
allergic reactions, especially in those allergic to garlic, onions, and tulips
- contact dermatitis or skin rash that develops after aloe vera is put on the skin
- phototoxicity, or a skin irritation similar to a severe sunburn
Diarrhea, vomiting, electrolyte imbalances, colic, and kidney problems have been associated with the oral use of aloe vera. Acute cases of some of these problems, while rare.
