Hair Serum
"Calecim Hair Serum is one of our best selling hair serums at the clinic and there is a reason for that. What we consistently notice with clients who follow the 6 week protocol is baby hairs growing back at the hairline, hair that feels noticeably denser, and hairdressers commenting on the difference without being told. It also works well for hormonal and stress related hair loss, which is where a lot of our clients are. Results are not overnight and they work best when the follicles are still active, so starting sooner rather than later makes a difference. Consistency with the protocol is everything."

“Two different technologies working toward the same goal. Use the PTT-6 protein a few nights a week and the exosome Hair Serum on the nights in between for steady, consistent scalp support.”

“If you are already using the Professional Serum on your face, the same PTT-6 technology is doing the work on your scalp here. Such an easy extension of a routine you have already committed to.”
Exosomes carry repair instructions between your cells, and they do their best work applied straight after microneedling or laser. Here is how they work and when they are worth it.
Growth factors are the signals your skin uses to build collagen and repair itself, and you make fewer with age. Here is what a serum can do and how it compares to retinoids and exosomes.
This is a stem cell–based topical treatment designed to improve hair growth by supporting follicle health and scalp rejuvenation. It contains Rejuvenating Conditioned Media, an ethically derived blend of proteins, growth factors, and exosomes from umbilical cord lining stem cells. These biologically active ingredients help reawaken dormant follicles, reduce inflammation, and improve scalp condition to encourage healthier, thicker hair.
This treatment is ideal for men and women experiencing early-to-moderate hair thinning or hair loss due to genetics, stress, hormonal changes, or scalp inflammation. It is also an excellent option for those looking to enhance the results of in-office procedures like microneedling, PRP, or laser therapy. It’s not a cure for baldness, but it can significantly support regrowth and improve scalp health when used consistently.
Some users begin to notice reduced shedding and improved scalp condition within 4–6 weeks. More visible improvements in hair thickness and density typically appear after 12–16 weeks of regular use. For best results, a series of weekly treatments, especially when paired with microneedling, is recommended during the initial 6–12 weeks, followed by ongoing maintenance.
While the Hair Serum is most effective when applied post-procedure in a clinical setting, it can also be used at home with professional guidance. Many providers offer it as part of a take-home protocol, especially for patients undergoing microneedling or laser treatments. It comes in easy-to-use vials for weekly or biweekly application, with no mixing or complicated steps required.
