I know this is a weird one but I just started using a new organic shampoo and it gives me a headache after using it. It feels like a bad sinus headache that must be from an allergic reaction to one of the ingredients. Are any of these ingredients known headache triggers?

Purified water, sodium cocoyl isethionate (derived from coconut), cocamidopropyl betaine (derived from coconut), tea tree oil*, argan oil**, black seed (kanoji) oil, amla oil, nettle extract, biotin, saw palmetto, cedarwood oil, rosemary oil*, sage extract, he shou wu (fo-ti), hibiscus oil, pygeum extract, pumpkin seed oil, green tea extract, zinc, soy isoflavones, beta sitosterols, aloe vera**, niacin, vitamin E, B-vitamin complex, phenoxyethanol (mild preservative), grapefruit seed extract (natural preservative), lactic acid (naturally occurring in yogurt), & dead sea salt.

rtd,   do you have CLUSTER headaches...or are you talking about an ordinary headache caused from the shampoo???   

I'm by no means a doctor or a chemist,    (my disclaimer)...but none of the ingredients in that shampoo have popped up here as a regular trigger. As Bonnie said, many of us are sensitive to certain smells while in cycle, my guess is the smell is a more likely trigger then the chemicals themselves.

Either way, if it consistently seems to bring on attacks, I'd just include it on your current triggers list. Stick around, keep reading and asking questions, we'll help you any way we can.
