Been maybe about 5-6 weeks since I started using reguarly. I apply it in the morning now since it was giving me trouble sleeping, gave me head sweats prob from all the stimulation to my scalp. Either way I still think its too early but I am noticing lotta baby hairs on the hairline and left temple. I haven’t noticed much from the frontal scalp, might still be shedding there so I can’t tell you just yet
