A 20-year-old with thinning hair has low vitamin D and normal testosterone. They are prescribed oral minoxidil and vitamin D, and are questioning if finasteride is also necessary.
Vitamin D tests like D2, D3, and 25-hydroxyvitamin D are discussed before starting hair treatment. Vitamin D can be obtained from food, but overdose has side effects.
Checking vitamin and hormone levels is important for addressing hair loss, as deficiencies in vitamin D, zinc, and iron can affect hair growth. Treatments like finasteride, minoxidil, and vitamin supplements are used, but addressing deficiencies is crucial for effectiveness.
Low Vitamin D can cause hair shedding, and taking 5000 IU of Vitamin D daily reduced shedding significantly. Vitamin D deficiency is common and correcting it can benefit overall health.
