HAIRNA Exosome Booster Ampoule is a ready-to-use liquid scalp booster built around purified adipose stem cell (ASC) exosomes, present at a 4% (approximately 37,200 ppm) concentration. The exosomes are paired with biotinoyl tripeptide-1, copper tripeptide-1 and growth factors to nourish a weakened scalp and support the hair growth environment. Supplied as a set of five 5ml vials with microneedle and a sterilizing container, it is typically used as a maintenance step that complements the HAIRNA Exosome Hair Fill.
What are ASC exosomes and how do they differ from plant exosomes?+
ASC exosomes are extracellular vesicles derived from adipose (fat) stem cells. They act as messengers carrying bioactive signals to scalp cells. This differs from plant-derived exosome products (such as rose-callus exosomes), which are sourced from cultured plant cells. HAIRNA Booster uses purified ASC exosomes at a 4% concentration.
How is the Booster Ampoule different from the Hair Fill?+
The Hair Fill is the primary treatment step that delivers exosomes and growth factors to balance and normalize the scalp. The Booster Ampoule is a maintenance product, usually applied after the Hair Fill, to reinforce the scalp between treatments and help prolong the overall result. They are designed to work together within the HAIRNA protocol.
What does the 4% (37,200 ppm) exosome figure mean?+
It refers to the concentration of purified exosomes in the ampoule – around 4% by content, expressed as approximately 37,200 parts per million. This is provided as a product specification to indicate the exosome content of the booster formula.
Why biotinoyl tripeptide-1 and copper tripeptide-1?+
Both are widely used hair peptides. Biotinoyl tripeptide-1 combines a collagen-fragment peptide with biotin to support hair strength, while copper tripeptide-1 is associated with regulating the hair growth cycle and supporting the scalp. Together with growth factors they form the peptide support layer of the formula.
What is included and who should use it?+
The set contains five 5ml vials together with a microneedle and a sterilizing container. It is intended for use by trained professionals on the scalp only. It should be avoided in pregnancy and breastfeeding, in anyone with known allergy to its ingredients, and on areas with active scalp infection. Patient suitability is assessed by the treating professional.

Brandon Lee –
Using this ampoule is so much easier than I expected. The microneedle applicator is painless and doesn’t irritate my scalp at all. It absorbs quickly without leaving any sticky feeling. I’ve tried other treatments before, but this one just feels more advanced and gentle.

I was seriously impressed with how quickly my order from fillersfairy arrived. I placed a bulk order of the Hairna Exosome Ampoule kit, and the shipping was smooth and fast. I could track the package in real-time, which made the whole wait stress-free. Everything showed up perfectly on time — no delays, no mess. Really happy with the service!
