Fucoidan hair growth agent

Abstract

To develop a novel administration method of a fucoidan-containing hair-growing agent and to provide a means for exerting excellent effects of a fucoidan.

A hair-growing agent of the present invention is characterized in that it is composed of a combination of a fucoidan-containing microneedle and a fucoidan-containing liniment. A base of the fucoidan-containing microneedle is preferably a biosoluble polymer. A hair-growing method of the present invention is characterized in that the fucoidan-containing microneedle and the fucoidan-containing liniment are concomitantly used.

Description

TECHNICAL FIELD[0001]The present invention relates to a hair-growing agent composed mainly of fucoidan.BACKGROUND ART[0002]Fucoidan is a kind of acidic polysaccharide polymers containing fucose sulfate as a main constituent sugar. Fucoidan is a viscous component contained in brown algae such as Undaria pinnatifida, Cladosiphon okamuranus and tangle weed, and is known to have a hair-growing effect.[0003]In relation to the hair-growing effect of fucoidan, a hair-growing composition containing fucoidan (Patent Document 1), a cosmetic containing fucoidan or a decomposed product thereof and having a hair-growing effect (Patent Document 2), foods and drinks containing fucoidan and having a hair-growing effect (Patent Document 3), a fact that a high-molecular-weight fucoidan having an average molecular weight of 1,000,000 or more is relatively effective for hair growth (Patent Document 4), an oral hair-growing agent with a combination of fucoidan and a seaweed-derived protein (Patent Docum...

AI Technical Summary

Benefits of technology

[0020]The fucoidan-containing microneedle of the present invention can exert a greater effect than in a case of using the conventional liniment alone.

[0021]Furthermore, by combining the fucoidan-containing microneedle administration and the fucoidan-containing liniment

Problems solved by technology

However, it is well known that even if a drug is orally administered, the drug is not necessarily delivered to a site of a body where an effect of the drug is expected to be exerted, and the utilization rate of the oral drug is low in many cases.

Also, it is well known that even if the drug is applied to a particular site of the body, a corneum acts as a barrier to drug penetration, and the drug does not sufficiently penetrate merely by applying the drug to the
