I love BT. I just got an order of it in this morning. BT is what made me pay my $5.00 cuz I had to tell y'all how good it was (to me).
If someone else in your family had a similar reaction to it, that might have been a clue to not try this product. Allergies/sensitivities often run in families.
Also, if you experienced discomfort ... why did you keep using the product? I would have immediately washed my hair, applied hydrocortizone to my scalp and got my butt to the ER - stat if I was feeling hot, burning, breaking out, etc.
Even if you don't have insurance, there are many free/low cost urgent care centers and ERs can't turn you away.
I'm not trying to come down hard on you, OP... but this product seemed like it wasn't for you, way before you even got it. And then when you used it and realized it wasn't for you, you continued using it. At some point, personal responsibility comes into play.
Natural products are not for everyone. A lot of people have allergies to sulfer. Many people have allergies to things like Camomile and honey. Remember that things like snake venom and bee venom (found in a lot of skin products now due to their swelling effects to plump up lips, fill in lines) are 100% natural as well but if you have any type of sensitivity at ALL... big problems are ahead.
Maybe you should consult a physician as soon as you can, and then stick to hypoallergenic/laboratory created products.
