Hair loss affects men of all ages, yet it can be especially devastating for those who begin losing their hair during their teenage years. Propecia, the brand name for the drug finasteride, received FDA approval as a treatment for male pattern hair loss, but only for those 18 years and older. Teens who experience hair loss have the option of speaking to their family physician to learn if Propecia can work for them.
Types
Hair loss in teenagers occurs for many reasons. Alopecia areata, the same type of hair loss that affects older men, can manifest in teenagers as young as 15, according to the Dr. Pistone Hair Restoration website. Another condition known as tinea capitis, or scalp ringworm, is a contagious fungal infection that leads to patches of lost hair and scalp inflammation. Traction alopecia occurs as a result of excessive hair drying, curling, bleach treatments and tight hairstyles. Though rare, male pattern baldness sometimes happens in teenagers as young as 14.
Finasteride
Finasteride belongs to a class of medications known as 5-alpha reductase inhibitors, according to MedlinePlus. Finasteride treats male pattern baldness by inhibiting the production of a male hormone in the scalp that prevents hair growth. Finasteride patients typically take one pill per day, as directed by their doctor. At present, finasteride is not recommended for males under 18.
PSA Levels
The FDA cautions that any changes in prostate specific antigen (PSA) levels --- protein produced by prostate gland cells --- must be evaluated by a medical professional immediately. PSA levels elevate in the presence of prostate disorders, including cancer.
Side Effects
Finasteride side effects include decreased sexual desire, inability to generate or sustain an erection, decreased volume of semen, testicular pain, increased breast size in men, as well as changes in the male breasts, such as lumps, nipple discharge and pain. Other reported side effects include rashes, itching, swelling of the face and lips and hives, according to MedlinePlus.
Considerations
Finasteride does not cure male pattern hair loss; it provides a means to control hair loss only. Given that the FDA only approves Propecia for men over 18, teenagers may consider waiting until they turn 18 to begin using it. Speak to your doctor or health practitioner if you are under 18 and encounter some form of significant or permanent hair loss.
