Castor oil: a powerful ally for hair growth

Also known and called castor oil, castor oil is extracted from the seeds of the castor bean, a species called Ricinus Communis, quite common in Brazil.

Some people know it for its medicinal use, especially for its laxative effect; others, due to their presence in cosmetic formulations, mainly in hair care products. But not everyone knows what benefits this oil can offer and what precautions are taken with its use.

Regiane Ribeiro, beautician at Clínica Goa Health Club, explains that castor oil is considered an excellent stimulator of the immune system, in part due to the concentration of fatty acids. “According to research, it can be used to treat diseases such as Parkinson’s disease, arthritis and rheumatism, cerebral palsy and multiple sclerosis,” she says. “But it can also be used to have benefits against constipation, yeast infections, menstrual disorders, migraines, inflammation,” she adds.

Sara Bragança, a doctor with a postgraduate degree in Dermatology, a member of the Brazilian Society of Aesthetic Medicine, specialized in Orthomolecular Therapy, highlights that the skin can benefit from castor oil. “This is because it has an emollient effect, penetrates the skin offering hydration and stimulating the production of collagen and elastin, thus acting in the prevention of wrinkles and expression lines”, she says.

Regiane adds that castor oil also acts to control hair loss. In fact, one of the most well-known uses of castor oil is for hair. Therefore, it is widely used in hair cosmetics.
