This is my personal view on the product:
To avoid scalp irritation-->
1) Washing frequently
2) Using another moisturizer with product
3) Not "over" doing it
-If you wash/condiiton wash or rinse your hair every day like at night and spray in the morning and after you wash, there should be no scalp irritation.
-Always try to put a "light" moisturizer on your hair in the middle of the day if the surge is causing severe dryness.
- Some people go crazy with the stuff by spraying 3 to 5 times a day. If you don't get any side effects from doing this then keep doing what you're doing, but if you are then calm down on the extra spraying for a while.
My experience-->
Once time I didn't wash my hair for three to four days or so. I sprayed the product on my hair twice and sometimes three times a day. The third day my scalp towards the back of my neck started to get very irritated and it left a red mark. I put some a & d ointment on my scalp the first day. The next day I washed my hair and my scalp seemed to be okay. Like I said, it depends on how you follow the directions and all. And then you have some people who's scalp doesn't have side effects at all. You make the decision. All in all, my hair has received 1 1/2 inches if new growth this month. I'm proud of this great progress, but I'm more worried about saving the good health of my hair.
