Sudden Hair Loss at 20 Years Old and Receding Hairline? (photo)

Losing 50 to 100 hairs per day is normal, and it doesn’t sound like you’re losing much more than that. However, it is smart that you’ve made a doctor appointment. Your best bet would be to see a dermatologist, and be honest about your medical history, family history, any drug use, dietary habits, etc. Though male pattern baldness is the leading cause of thinning hair in men, several other things can contribute to hair loss, like a traumatic emotional event, severe stress, alopecia areata, malnourishment, anemia, diabetes, and more. Once a diagnosis is made, a course of treatment will follow.

getting a medical evaluation is the best first step then go from there. once your doctor has cleared you then proceed with some hair loss treatments such as finasteride or minoxidil, your physician will be able to assist you with this.

Any sign of sudden hair loss should be evaluated by a physician familiar with hair loss and hair restoration. In many cases, patients are simply noticing more hair loss than they have noticed previously, but the rate of hair loss has not changed significantly. 
It is normal for the hairline to recede somewhat over time for men as they age from their teenage years. It is also possible for other factors to contribute to hair loss, or for a medical problem to be causing hair loss. A formal evaluation with a hair restoration specialist, facial plastic surgeon, or dermatologist would be recommended. If androgenetic alopecia is diagnosed, hair transplantation may be an option in the mid-20's.
All the best,

Normal male hairline progression from a juvenile to a mature one typically starts during puberty to their late 20s.Hair loss does not come on "suddenly".  You probably had some degree of hair loss over the years and now passed a threshold to notice a change in your appearance.You can ask your doctor for a miniaturization study.

In general, if an individual normally has 5-10 hairs lost per day and suddenly notices 100-150, it is abnormal. There is no better judge of what is "normal" for a given person, than the person themselves. Hair shedding can occur during male balding but can occur in several other conditions as well. It is a great idea for anyone with excessive hair loss to check in with their physician. In general, a physician who is knowledgable about the many many types of hair loss will guide the questions.  Patients should come with lists of medications, family history and previous photos if themselves ( if possible). It is important to share information about speed of hair loss, scalp symptoms (itch, burn pain), diet, medications, stress, family history of hair loss, medical history, allergies

I think your best option is to see a board-certified dermatologist. This is the specialty that focuses on diseases of the skin, hair and nails. Let the dermatologist ask the questions and examine you. It is normal to lose between 100-150 hairs per day, but if there are "clumps" of hair falling out, there may be another problem to treat. The doctor will evaluate your hair loss by history and physical examination and may do some laboratory tests to come up with a diagnosis and treatment plan. Don't worry and good luck.
