Shea butter is a miracle ingredient in the beauty world for hair. But have you ever wondered about the science after the benefits of Shea butter for hair? Then this blog is going to be so interesting for you. Some studies or research-based literature explain why and how this ivory and creamy substance improves the health and appearance of hair excellently.
For thousands of years, Shea butter has been cultivated for food, medicine and especially for beauty. In today’s world, where most beauty products are made of chemical procedures, Shea butter is a product that is a pure, natural, healthy and pristine moisturizer for both skin and hair.
Now you will get the reasons and way, it can benefit, based on the result revealed by scientific researches. So, go through the passages below.
The fact behind moisturizing
Human hair is nothing but fibrous, so it can’t hold water is not an obvious conception. Actually, water is one of the important ingredients to make each of our hair, and the amount is 10-13%. It is present in the intricate protein structures of the hair shaft, especially in the cortex. The rich moisturizing quality present in Shea butter because of the high fatty acid content, and it includes oleic and stearic acid as well as linoleic, arachidic and palmitic acids. These properties make hair optimal to prevent water loss and even the hair breakage problem.
The relation of hair growth
The inflammation of the scalp is not only a reason for itchiness. It damages hair follicles too. As it causes hair loss, it can also prevent the production of new hair strands.
Shea butter is not only supportive of hair stands, but it also has the properties to moisturize, condition, alleviate inflammatory concerns affecting the hair follicles. Studies found eight individual constituents in Shea butter that are four triterpene cinnamates and four triterpene acetates. Each of these constituents is able to inhibit inflammation.
Shea butter and Sun protection
The detrimental effects of UV radiation from the sun on scalp and hair are partially evident through the availability of sunscreen products for hairs. And it is growing and spreading widely.
In ‘The Impact of Oxidative Stress on the Hair’, a scientific review article, the author R.M. Trueb points at the topic of oxidative damage to the hair. He highlights, sun rays cause the lose of a single electron in oxygen molecules and turn them into free radical scavengers, which cause oxidative injury to nearby tissues of a chain reaction as they try to recover the missing electron.
According to scientific researches, a carefully formulated mixture of Shea butter can add sun protection properties because of the ingredients of cinnamate esters of triterpene alcohol. It can absorb the UVB radiation between the ranges of 250-300 nm wavelengths. This non-greasy product also protects scalp and shafts from more harmful effects from sun exposure.
