No one test is really worse than the other on the hair. But when you start getting into Deca it's a little worse for most people. tren quite a bit worse and for some reason Masteron is a LOT worse
Actually you lose hair not as much because of test as much from dehydrotestosterone. Test is only kind of a prohormone. It is converted into DHT by 5-alpha-reductase. You can control its convertion by using reductase inhibitors. However they can have some side effects.
