Check with your surgeon on what he or she recommends. In general, it's not OK to wash one's hair normally - it must be done in a very delicate manner. There are dozens of different ways one can wash the hair after surgery - but they all follow the same principle - be delicate not to dislodge the precious new grafts. Some surgeons recommend taking a cup of soapy water and gently rinsing it over the grafts, some recommend putting a wet facecloth on the scalp and letting soapy wanter run down, and other recommend lathering soap in one's hands and gently patting the new hairs. All these techniques achieve the same thing - gently remove debris and blood and moisturize the scalp. With the exception of medicated (2 in 1 shampoos) and highly scented shampoos, most routine shampoos are OK - but check with your surgeon first.
