I dont remember what I read about the lysine. It was enough to scare me. Which doesn’t take much with regards to supplements and medications. Daily I take biotin 5mg, omega 3 fatty acids 600 mg, of course calcium and vitamin d bc of my age and 200 mg of magnesium bc I get headaches. I use free and clear shampoo bc anything else gives my scalp a burning reaction. Once a month I use a dandruff shampoo with Pyrithione zinc bc of the dermatitis. Sometimes I get a reaction (Burning) sometimes I don’t. It might be bc sometimes the dermatitis might be extra sensitive all I know is I can’t use the steroid Fluocinonide topical solution bc either I have become sensitized to it or allergic but it’s what the Derm wants me to use which I don’t. Also prescribed is ketoconazole 2% shampoo (generic for nizol) which I haven’t used yet bc I’m afraid of a reaction. I never used to be afraid of anything I used until I became sensitive to things now it’s almost a phobia. That’s why I was nervous about the lysine bc of one article it was also related to the reading of getting too much vitamin A. (The cilantro) I was taking sumatriptan for migraines and that’s when I noticed the hair thinning. Now I only use that if the headache is so bad it makes me forget about the fear of hairloss but even that medication is ok as long as it is not excessive same for biotin and of course lysine and vitamin A. My hair sheds in the summer. It’s like clock work when it starts getting sunny. And again like clockwork when it’s fall it sheds less. It’s normal shedding and I’m assuming my age 51 it’s Normal for it to thin not in my 20’s anymore. But it does break easily around the hairline. I get frustrated dealing with all this. You would think I would be relieved it’s not Grover’s which I am but it’s the same things to deal with the itch and the bumps as Folliculitis.
