I am 3 weeks post op from a hair transplant surgery and am looking to get some Biotin Spray to help with recipient area redness. Thank you for your inquiry. Individual who undergo hair transplant surgery for hair loss, particularly those who have a large procedure are prone to redness after surgery. Individuals with fair skin or skin that is pink prior to a procedure are more prone to post-operative redness. Redness is a sign of inflammation. Hair cycle products are designed to reduce inflammation and redness. We will be happy to send you some biotin spray as this may help to speed your recovery and reduce redness. It helps to get rid of scabbing and redness faster. It has also been reported to promote faster hair re-growth. In order to get the most benefit of the Biotin spray you should begin using it every hour during your procedure and continue a light mist of the recipient area every hour after the procedure while awake. Don't worry about waking up every hour while asleep. A full night's rest is important to the healing process too. Since you are already three weeks out from your procedure, you will not get all the benefits of the Biotin Spray. Still it is good to begin using it now as it is very healthy for you grafts. Don't forget that the shampoo and conditioner are very healthy for your hair and your hair loss. The shampoo has been reported to speed the growth rate of hair. This can be very important to those with thinner hair, particularly those with fine hair or those with hair loss.
