6 months after combined FUT+FUE still slow/weak growth on the right side of the frontal area, what can I do? (Photo)

It can take 6 to 12 months after surgery to see results.  If you are concerned it is best to contact your doctor

At 6 months your have 50% of the final aesthetic result as there will be a increase in shaft diameter. Be patient and assess results after a year. 

Hey there,A PRP session may help hair growth. Continue hair growth supplements. Sometimes transplanted hairs take a little longer to grow.
Hope this helps.

A few things to consider in such a situation:
First of all, it is a very common activity for one side of a hair transplant to growslower or "lag" when compared to the other. This is natural and everything shouldeven out by the 12 months mark.Secondly, are you taking any preventive medications? Patients sometimes tellsabout "thinning" of transplanted hair or one area of a transplant (particularly in aregion prone to progressive androgenic alopecia) growing poorly, and it is oftencaused by progressive loss of native hair surrounding the implanted grafts. Thisresults in an overall thinner appearance or the perception of poor yield.
Third, at 6 months, your grafts are only roughly 40% matured. This means growthrates are still different and new hairs may still appear thinner and "wiry." Becauseof this, it really is important to wait a full 12 months before fully evaluating theresult.
Hope this helps!

I don't want to alarm you but there are many variables that could be going on here. I do see the weaker growth on the right side as apposed to the left side. I hope this wasn't a technician issue where upon the left side was placed by an experienced technician and the right was placed by a less experienced technician. Or it could be simply that you need to scrub during a shampoo more aggressively as that there are hairs trapped that need to shed. 
But time will tell as it is still quite early post op to tell full growth at this time.

Be patient, you need to wait 6-8 more months for the final results. I have seen many patients with slow and uneven growth then full growth after that. Also are you in any medical hair loss treatment? This is VERY important to maintain your existing and non-transplanted hair. Good luck.

Hair goes through a cycle of growth and comes in gradually after hair transplant. It may take up to one year to get the full results. You need to be patient and wait. 

You must wait it out for a full 8 months when 80% of the growth can be seen grown to styling length
