My 10 year old daughter who started puberty at age 7 and has had monthly periods since age 10{BDAY next month} has red hair. It used to be so silky and curly. Now it's really coarse and she has developed this weird "cow lick" and where it's situated she has a huge kinky mess. We blow it dry and use a straightening iron after she washes it but this one section is horrible. She has been tested for thyroid as I have thyroid problems.
It's bad enough when we get older but then everything else goes to pot. I hope you can get your hair problem fixed. The lady who cuts my daughter's hair suggested mink oil spray, which can be bought at Walmart.
Good luck,
Bonnie
I'm afraid I don't have any specific information to share with you. Over the years I have had a few patients tell me that their hair texture changed during periods of hormone changes--pregnancy for instance--from straight to curly or the reverse. However, I know of no diseases or syndromes which cause this, nor of any treatment. If the dermatologist who examined you didn't find any hair disease per se, I'm afraid I don't know of one either. Sorry.
