I apologize in advance if this topic has already been discussed. I am new to the forums and need advice. I know someone (a hairdresser) who just highlighted 5 kids hair and they range in age from 2 years to 13. Putting aside the debate over how soon is too soon, self-esteem and the like, my bigger concern is the absorption rate of children's skin being so much higher than that of an adults and the potential harm it can do. Remember the warnings about bug sprays, sunscreens, and more 25 years ago? Hmmm...what do you think?
