22 Year Old using only 5% Xandrox?

[z_eix]

I am 22 years old and have been thinning for the past year. I have good coverage when my hair is dry, but when I gel, it looks very thin. My crown and temples are going faster. I had an online consultation with Dr Lee and he said I should have good results with his 5% Xandrox. I am also using Nioxin Shampoo daily and Nizoral 3 times per week. I will start my Xandrox next week. My question is about a shed. My hair is very light and seems to just wave in the air. What kind of shed should I expect? I am a car salesman and cant wear hats so I am worried I will look horrible. Help Please!
