岡嶋教授らはこれまでにトウガラシの辛み成分、カプサイシンが知覚神経を刺激、毛の成長を促進するたんぱく質「インスリン様成長因子1（IGF-1）」を増やす仕組みを解明している。
他にもＩGＦ-1を増やす物質はないかと考え「牛に頭をなめさせると毛が生える」というドイツの言い伝えに着目。唾液中のシアル酸(Neu5Ac)にも神経刺激作用があることから、育毛効果があると考えた。
実験はマウス10匹の背中の毛をそり５匹には普通の餌を、別の5匹にシアル酸を経口投与。4週間後、普通の餌を与えたグループはまだ背中の地肌が見えたが、シアル酸を投与したマウスは毛がほとんど元通りだった。
薄毛の男性10人の頭皮に毎日1回、直接シアル酸を塗ると半年後、5人に育毛効果が表れ、女性10人のほおに4週間塗り続けると7人に肌の弾力がアップする効果もあったという。
Good news for people suffering from thinning hair? Professor of Graduate名古屋市立大Okazima Kenzi (55) Associate Professor, Department of Medical Science Harada Naoaki and expand (41) = at = a, saliva (sputum) a type of sugar in "sialic acids" have an effect on hair growth found that. Make sure the skin effect, which is expected to be used to develop the serum and hair restorer. Experiments on mice results announced Monday by the Japan Society of Agriculture.
Shima Oka professors are hot flavor of ingredients so far TOUGARASHI, capsaicin stimulates the sensory nerve, proteins that promote the growth of hair "insulin-like growth factor 1 (IGF-1)" to clarify the mechanisms that increase.
And IGF-1 and other substances that increase the "hair grow and make the cow licked the head," focuses on the legend of Germany. Sialic acid in saliva (Neu5Ac) from that impulse to action, we will have the effect of hair growth.
Experimental mice hair 10 sled dogs in the back of the animal's regular food, the sialic acid by oral administration to five dogs. After four weeks, the group was given normal feed back地肌have yet appeared, mice were administered a sialic acid was the most original hair.
Thinning hair on the scalp of the 10 men who once daily, after six months and apply directly to sialic acid, shows the effect of hair growth in women 10 to cheeks painted four weeks and seven remain effective up to the elasticity of the skin was.
