Hair loss by age or can hairloss stop?

Dear antikkopmaThanks for the question. Normally, hair loss starts between the ages 18-25 in most men. When a man passes his 35-40 age, hair loss usually slows down and after the age of between 50-60, it increases again. This information shows us that the process of hair loss is progressive and throughout life. But there are always exceptions to the rule.That's why It is always more efficient to have a medical examination. But hair transplantation is permanent and always offers successful solutions. I wish you all the best.

You are at risk for further loss as you have identified. You'll want to speak to a hair specialist for options including finasteride, minoxidil, laser and PRP. At 20 years of age, you are not a hair transplant candidate quite yet. 

If you genetically resembkes your father , it is quite logical to expect a baldness nw 4,5 in future but no one can say that %100 .İt is biology and there is very much differentiating factors. İt is better to use finasteride to stop hair loss although I dont recommend it to my patients because of possible side effects .

Genetic male patten hair loss the most. Common cause of hair loss. If your dad is 4-5 on the Norwood scale of hair loss and you already have thinning, your hair loss is most likely going to progress. You can see a hair loss specialist and get recommendations to slow down the progression of future hair loss. 

Your biggest enemy is the
progressive thinning leading to a balding pattern that is not evident at this
point in time. The degree of thinning that you are experiencing would suggest
that you should see a doctor who most likely will get Bulk Measurements of your
hair to determine the degree of the thinning that you are presently having. If
the diagnosis is early genetic hair loss (the most common cause of hair loss in
young men), then the best treatment would be the drug finasteride which is
highly effective in men of your age and may not only stop the hair loss but
possibly reverse it. If you are developing a more advanced balding pattern the
best test to get will determine the Bulk Measurements of your hair and this
will show, over a one-year time frame, how effective the treatment will be.
Once you know this information, then you and your doctor need to develop a
MASTER PLAN which will define what you need to do over the years to come.
