My age is 24. Should I go for hair transplant or not? (photo)

Hair transplant surgery is not about "how many grafts" you need, but about how a doctor can match your goals and expectations.If you are considering surgery it is best to see a doctor for an examination and consultation.

Although it is a bit difficult to judge from the photos you posted, it seems like you have a significant amount of hair loss more in keeping with the Norwood Class A pattern (where hair loss happens from a front to back direction), rather than the much more common regular pattern (where hair loss begins in the temples and vertex of the scalp).  Given the quite early age of onset, and assuming  no other cause for hair loss such as medications and illness, you may be looking at significant hair loss in your 30s and 40s. Remember that hair loss can happen in cycles, where your hair may stabilize after an initial  period of loss, and then the loss starts up again.  The important consideration here is to make sure you have male-pattern alopecia, rather than the less common Diffuse Unpatterned Alopecia condition.  Although they can look exactly the same in the early stages (such as you have now), in male-pattern alopecia the hair on the back (occiput) of the scalp remains stable and can be safely transplanted, giving great, long-lasting results.  In the Diffuse Unpatterned Alopcia condition, the hair on the back of the scalp is NOT stable, and will gradually thin out as well, making it unsuitable for transplantation.  The only way to tell is to wait it out a bit until your late twenties/early thirties, and your doctor will have a much better idea if your occipital scalp hair is stable or not.  Hair transplants are expensive.  They work really well in the right patient, but not if you have Diffuse Unpatterned Alopecia, because you don't have any stable donor hair.  Make sure you don't throw away your hard-earned money.  You need to continue the medications - Finasteride and Minoxidil - as long as there are no side effects - to preserve whatever hair you have left, and delay any surgery until you are at least in your very late twenties.  I hope this helps!

Before starting with a hair transplant, I would try the drug finasteride for a year which may reverse the hair loss. If it does not work, then a hair transplant is a reasonable option
