I did the PRP hair growth treatment at One Aesthetic Lab, and honestly, I’m super happy with the results. The team is friendly, professional, and really knows what they’re doing. My hair feels thicker, and I can actually see new growth coming in. It’s rare to find a place that’s this honest and detail-oriented. Definitely recommend them if you’re serious about your hair.

I was honestly nervous about the O-Shot, but the nurse made me feel safe and comfortable from start to finish. The whole process was quick and handled with real care. Within weeks, I noticed improvements I didn’t think were possible. It gave me back a sense of confidence I’d been missing.
