My 9 year old daughter has been losing her hair for the past 8 or 9 months. The trichologist said it was low iron and low vitamin D. The dermatologist said it was telogen effluvium and prescribed luxiq (topical steroid). The pediatric endocrinologist was useless but did tell us he did not see a thyroid problem. The thinning is diffuse and really starting to show now. Other factors: She gained a lot of weight suddenly in the past 2 years or so; we have a family history of hypothyroidism; she has joint problems in her knees and ankles occasionally; and she had a fever about 3 months before I first noticed the thinning and she had her tonsils out about 2 months after I first noticed the thinning. Recently we started her on iron, vitamin D, omega 3, probiotic, vitamin c + b complex, biotin (and biotin and tea tree shampoos), and silica. Also weekly castor oil and coconut oil hair treatments. Can anyone recommend a specialist within 100 miles of DC? Or take a guess at what's wrong and/or how to fix it? Or suggest other natural remedies? She had lots of lustrous curly hair until 9 months ago. I am worried that we are missing some underlying disease that is progressing. Thank you to anyone who can help.
