黑色的秀髮，最主要是由真黑素(Eumelanin)天然染成。576Please respect copyright.ＰＥＮＡＮＡZRJiR1g8ZH

（圖2）皮膚下的黑素細胞(Melanocyte)會製造出黑色粒子Melanosomes，而這些黑色粒子Melanosomes會走到表皮(Epidermis)或者髮囊(Hair follicile)，賦予皮膚及頭髮黑色外表。576Please respect copyright.ＰＥＮＡＮＡXRQKEaXBIq

（圖3）圖中為Melanosomes裡頭的生物化學反應，起始材料為氨基酸，經過一輪酶素的化學反應後，最終成品將為黑色真黑素及啡色真黑素。576Please respect copyright.ＰＥＮＡＮＡ2SdZdzSASo

而根據兩者比例的不同，最終的顏色效果亦會有所不同，所以Melanosomes並不一定是純黑色，亦因而解釋了為何並不是所有人的頭髮也是漆黑黑一片。576Please respect copyright.ＰＥＮＡＮＡ6NmEd2jrFs

值得留意的是，這一系列發生在Melanosomes的反應均是在中性pH7的環境下進行，有別於現時常用的鹼性pH化學染髮方式。576Please respect copyright.ＰＥＮＡＮＡyYBlWLuJb6

有科學家看準這一點，因而嘗試照辦煮碗在體外套用我們自身Melanosomes蛋白酶的機制方式進行染髮（Ref1)。576Please respect copyright.ＰＥＮＡＮＡdxMnUAAWFj

（圖4）從圖中可見，鹼性pH化學染髮以及中性pH7模仿人類Melanosomes裡頭生物化學反應方式染髮（2小時，攝氏35度），兩者最終的外表差別不大。576Please respect copyright.ＰＥＮＡＮＡvw8rf5UyWM

而且經過5次清水沖洗及10分鐘的洗髮水猛烈沖洗後，兩者亦沒有出現脫色的現象。576Please respect copyright.ＰＥＮＡＮＡYI7bQnjIcJ

只不過，利用鹼性pH化學染髮的話，色素會徹底進入髮質內部。576Please respect copyright.ＰＥＮＡＮＡtyDiB901aI
反觀中性pH7生物化學反應方式染髮，色素主要聚集在髮質外部，因此對頭髮的傷害相對較低。576Please respect copyright.ＰＥＮＡＮＡVGwuV9vTjw

（圖5）在圖中亦可以清楚看得到，鹼性pH化學染髮對頭髮外部會做成傷害(箭嘴所指位置)，576Please respect copyright.ＰＥＮＡＮＡ0L9tmnOv1V

576Please respect copyright.ＰＥＮＡＮＡVerPbzATL2
而中性pH7模仿人類Melanosomes裡頭生物化學反應方式染髮則沒有這個問題。576Please respect copyright.ＰＥＮＡＮＡH0OiaV9xs4
576Please respect copyright.ＰＥＮＡＮＡOLG7qEyqTN
此方法能否在日後淘汰鹼性pH化學染髮或其他的染髮手段，我們將可拭目以待。576Please respect copyright.ＰＥＮＡＮＡuDp4kLRbOp
