"Cholesterol hair treatment is a deep-conditioning treatment that involves the use of ingredients that are rich in fat on the hair and focuses on harnessing the benefits of cholesterol for your hair.
While cholesterol gets a bad name for causing metabolic or heart issues, it has been suggested to play a part in the growth of hair and maintaining its overall condition.
Your hair grows from tiny structures called hair follicles. Cholesterol is thought to contribute to the functioning of these follicles. (2)"

"Cholesterol is a fatty substance that plays an important role in certain areas of the body, including the skin and hair.
Cholesterol is a waxy, fatty substance present in many animals, including humans. People can also use this substance in external treatments for areas such as the body and hair.
Cholesterol treatments may help seal the hair and protect it from damage or give a more natural look to damaged, overprocessed hair."

"Anyone can benefit from a cholesterol treatment for hair growth. They were traditionally used to repair the damage caused by chemical processing. However, there are several benefits of cholesterol for natural hair, as well. That’s because cholesterol also helps to repair the damage caused by heat styling and over-manipulation of the hair."

"A cholesterol treatment is exactly what it sounds like: a hair mask or deep conditioner that is useful because of its cholesterol content. It’s rich in lipids and fats which aids in hydrating and moisturizing your hair by coating and deeply penetrating each strand.
The fact that cholesterol treatments are fully of lipids is super important because our cuticles rely on three main lipids—ceramide, cholesterol, and 18-MEA—to stay flat and healthy enough for proper hair growth and moisture retention.
So, in short, a cholesterol treatment is a thick, creamy deep conditioner formulated with some additional beneficial fats."

"Hair cholesterol is a natural moisturizer and the treatment helps in repairing and restoring moisture to damaged and dehydrated hair. This treatment has been used by American and African communities for decades to restore softness and moisture after repeated styling processes."
