3 weeks post FUE, need advice regarding creatine use, LLLT, and best shampoo to use for optimal growth. (Photo)

3 weeks p/o FUE and I am using propecia, minoxidil, and biotin supplements. I get dry skin post minoxidil, can I use babyoil after to keep hair moisturized, how long after minoxidil use? Can I take creatine containing preworkout for the gym like C4 ultimate? Currently using baby shampoo for 1st month, what shampoo considered gold standard for max hair growth, caffeine containing/DHT blocking? LLLT (iRestore) use post fue studies/publications and recommendations. Thanks in advance for your help.
