It relates to a composition capable of improving the condition of the scalp and hair.

Recently, interest in appearance has increased, individual desire to express individuality has increased, and hair and overall body beauty are considered as important as facial makeup. The frequency of use of the same hair styling product is increasing.

However, hair styling products such as dyes and perms can cause hair damage, and in the case of some sensitive scalps, chemical treatments such as dyeing and perming may cause scalp irritation or inflammation such as itching or stinging of the scalp. Various products such as hair essence, hair spray, and hair toner are being researched and developed to improve scalp health.

On the other hand, hemp ( Cannabis sativa L. ) is one of the earliest cultivated plants in the world. there is.

In particular, the fiber obtained from the stem of the hemp is used for manufacturing ropes, fabrics, and paper, the seeds are used as a raw material for manufacturing various foods and cosmetics, and the leaves (cannabis) are used for rheumatic pain, constipation, women It is an important plant used as a drug for the treatment of reproductive disorders, malaria and others.

However, hemp leaves consist of more than 460 chemicals, and tetrahydrocannabinol (THC) contained in hemp is the main psychoactive ingredient, so even small amounts can cause strong hallucinations. The use of cannabis is legally restricted in most countries as it can cause serious side effects, such as hallucinations and paranoia, as the US, UK, and most European countries designate cannabis as an illegal narcotic. Cannabis use is illegal in most countries, with the exception of some countries that do so, and in Korea, not only smoking but also cultivation and distribution are strictly controlled.

Recently, unlike hemp leaves, which are subject to legal regulations, hemp seed contains almost no hallucinogenic components such as THC, and it is known that hallucinogenic components are also removed during the process of removing the skin of hemp seed. In particular, as it is known that hemp seed has a high content of protein and unsaturated fatty acids, essential amino acids are evenly distributed, and has various physiologically active functions such as skin improvement, various methods for utilizing it are being sought.
