Before and after images and study data supplied by mesoestetic. Individual results vary.
“I noticed less hair loss. The colour of the hair is more intense, and the grey hairs are less visible.”
“My concern had to do with my fragile and thin hair. I notice my hair stronger and thicker. I'm now aware that I have to follow a daily hair routine to maintain the results.”
“I noticed less hair loss from the beginning. I perceive more density in areas where I initially had thinner hair, and I have noticed hair growing in the receding hairline.”
Testimonials supplied by mesoestetic. Individual results vary.
Plant-based exosomes are small vesicles containing bioactive substances that help the microenvironment around them work properly. In mesoestetic's range, they are exclusive to tricology lotion and the in-clinic c.prof 231 dutexome solution.
Plant-based exosomes and targeted actives to fortify the hair and help control hair loss.

Serenoa serrulata fruit extract, in the lotion and the shampoo.
Melatonin, vitamin B6 and a biotin and dexpanthenol complex for hair vitality.
Zinc in all three products, plus mesoestetic's 5α-BLOCKER® complex in the capsules.
tricology lotion is water-based and light, so it absorbs without leaving hair greasy when used at the recommended dose.
tricology caps are a daily food supplement with plant extracts, biotin and zinc, designed to complement the lotion and shampoo. Biotin, selenium and zinc contribute to the maintenance of normal hair.
The A20 is Dr. Pen's professional pen, designed for controlled, consistent handling. AVOS vertical oscillation keeps needle movement steady, and the LED digital display shows your speed setting at a glance.
On dry hair, apply one third of a tricology lotion vial to the scalp, parting the hair and tracing lines. Massage until absorbed and leave on overnight. Use one vial a week.
Take one tricology caps capsule before breakfast with a glass of water.
Massage tricology shampoo into the wet scalp, leave on for 2 to 3 minutes and rinse. After a lotion night, wash with it the next morning.
Follow the A20 instructions: fit a new sterile A20 cartridge, choose your depth and speed, and work in sections. Use a new cartridge every session.
The tricology products are for your at-home routine and are not intended to be needled into the skin. Follow the device guidance or your practitioner's advice on when to restart them after a session.
