After reading my journals and doing some research I wanted to ask you guys what you think about the following. If this has already been addressed, please disregard.
Lavendar, peppermint and cinnamon oils all cause cytotoxic (Cell death) when applied topically. They all are cytotoxic to human skin. It also increases photosensitivity.
You ask, "Well, they are in otc products so they must be safe, right?" The cosmetic industry is not regulated. Products are not tested or reviewed before they reach the shelves. I would like to believe that since cosmetic chemist already know this, they would use the least amount possible to add fragrance or sensation to the product.
When a product list A,B,C,D,E as the first five ingredients, the total of the five could be as follows A=90%, B=5%, C=1%, D=1%, E=1% and .1 for all others listed on the bottle.
Because LHCF members have such a passion for growing long beautiful hair and are DIY'ers, I felt this was something I wanted to share, so we all can remain safe and healthy on this journey.
I'm not suggesting you throw anything out or to stop using it. I'm merly sharing food for thought.
Until we know what ratio should be used, I would suggest we only use a drop or two of the listed oils to be sure we don't cause cytotoxic. What do you guys think?
Cytotoxic
Treating cells with a cytotoxic compound can result in a variety of cell fates. The cells may undergo necrosis, in which they lose membrane integrity and die rapidly as a result of cell lysis. The cells can stop actively growing and dividing (a decrease in cell viability), or the cells can activate a genetic program of controlled cell death (apoptosis).
Photosensitivity
Sensitivity of the skin to a light source can take various forms. People with particular skin types are more sensitive to sunburn.
