5 months post ARTAS FUE. 750 grafts. Should it be thicker by now?

Thank you for posting this question. Due to the nature of hair follicle physiology, your hair follicles are only starting to return All hairs have cycles; anagen (the growth phase - 3-8 years), catagen (the regressive phase, in which the follicle sheds its hair - about 2 weeks) and telogen (the resting phase - 3-8 months).  All of everyone's scalp hair is cycling according to this schedule. Starting at about 3 months or so, the transplanted follicles will come back into their growth phase asynchronously. That's the key word: asynchronously.  As in, starting in about month 3, some of the follicles will return to the anagen phase, with more growing in month 4, 5, 6 and so on. The final result is usually seen within 12-15 months. Nobody would expect a final result at just 5 months. I hope this information is helpful to you.

It is not uncommon for growth to start 4-6 months after hair transplant. By 6 months, you should begin to see growth, so if you are at 5 months post-surgery then I would monitor a little longer. If you do not notice growth at 6 months then I would follow-up with your surgeon.

After a hair restoration procedure, three quarters of the newly transplanted hairs will likely fall out in the first few months.  The actual follicle itself does not fall out and continues to produce a new hair. Because of this the first of the new hairs will not be evident until the fourth month after the transplant was performed.  Each month thereafter new hairs will then begin to grow. Some of the new hairs will not grow until about a year. By about the sixth or seventh month you should begin to see the results of your transplant.  But remember, the final result will not be apparent for 12-15 months.  If you have a concern though it is best if you contact the surgeon who performed the procedure.
