Eyebrow transplant done three days ago. How long before the scabs come off? Can I start washing the brows?

After an eyebrow transplant procedure, it is quite normal to
have crusting or scabbing form around each hair for about two to four days. And
in three to five days, the skin will continue to heal to the point where the
signs of surgery are barely noticeable, if at all. Cleaning the area is best done in the shower,
where water can gently run over the treated area. This should be done two times
a day for a week after your procedure. After your showers, apply an antibiotic
ointment which can help soften the scabs and facilitate their removal.

Speak to your doctor about the concerns you have over the
shape of your eyebrows. It may (or may not) be necessary to revise your outcome through a
repair surgery. 

Follow up with your doctor if there is increased scabbing and it is the wrong shape.  It is important to see your doctor about these serious concerns.  The Internet is not a source of post operative care.

The crusts should have been taken off on the first day following the transplant. Washing daily, but not picking the crusts is what you must do until the crusts come off by themselves with the shampoo
