Query: Great in your 40's

My hair dresser introduced me to TOPPIK to go along with my Rogain. Both are great but together over time they have cured 80% of my hair loss isses which is amazing. A little TOPPIK on your scalp dulls and colors your exposed skin and thats all i needed to solve the ballance of my issues. Works good
