Shock loss 3 months after FUE Hair Transplant, how long will this last?

Recovery from Shock loss can take up from six months to a year. Shock loss is due to the loss of normal hair whether it is from donor site or recipient area.  It can occur with both FUE and strip procedures.  Usually if it occurs it will take place in the recipient area.  
Shock loss from hair transplant can occur due to the following:
Anesthesia-  excessively long procedures taking longer than 12 hours can induce shock loss more likely.  the repeated use of lidocaine, marcaine, and perhaps most importantly epinephrine can affect nourishment of the hairTraumatic harvest-  In strip surgery, traumatic harvest can induce shock loss.  Recipient area trauma- during the incision making process the hairs are either crushed or cut and damaged during the process.Ways to minimize shock loss are as follows:
Improve recipient bed and donor area environment.  Make your recipient environment improved by addition of growth factors and/or PRP to help reduce incidence of shock loss to native hairs.Use of Rogaine and Propecia- can help miniaturized hair become more stable and less likely to fall out during procedure9xRobotArtas-  The latest version of the robot can make recipient sites and can determine angle of existing hair and help ensure that the angle will not damage existing hair.  Especially helpful in patients where you are transplanting hair to create densityMinimize anesthesia time and procedure time- We limit number of grafts to a safe number per session.  Extended anesthesia periods and harvest times can cause patients to have a higher chance of shock loss.  The 9x Robot harvests between 1000-1500 grafts per hour making it superior to previous additions and traditional FUE approaches.Best,

If you are losing hair it is best to follow up with your doctor for an assessment.  You may be experiencing continued genetic hair loss versus shock hair loss.  

You are using Minoxidil. So it is hard to say whether it is the hair transplant causing the hair loss or Minoxidil or combination. Unfortunately, shock loss does after hair transplant at times.  Propecia does help decrease shock loss associated with hair restoration. I would also recommend a special protein shake and multi vitamin called "Help Hair". You take one scoop of the protein in the morning and one multi vitamin at night. I have noticed this also helps as well. Thank you.

If you are experiencing shock loss the hair typically begins to grow back in 2-4 months in the new growth cycle.

It's normal to lose some hair after the on-set of Minoxidil, as it resets the growth cycle. Typically this is a good indication that the medication will work for you and the hair should grow back stronger.  It will likely take 3-4 months for it to begin to grow back.
