Dr. CYJ Hair Filler 1ml comes from the Korean brand Dr. Cyj and is a slow-release injectable complex placed in the scalp through a series of microinjections. It is designed for scalp care in men and women whose hair looks thin, fragile or brittle, and it is supplied as a single 1 ml unit.
The base of the formula is reticulated (cross-linked) hyaluronic acid at 0.7%. Around this, the manufacturer has built a blend it describes as seven groups of peptides and supporting actives:
Dr. Cyj states that the gel combines biphasic and monophasic physical properties, and that its ingredients are released gradually after placement rather than all at once. The hyaluronan component is there to hydrate the area around the follicles.
The product is placed by microinjection across the areas of the scalp chosen by the practitioner. Typical candidates named in the sources are adults with fine or brittle-looking hair. The manufacturer also mentions it alongside other scalp care approaches, including for clients who have previously had a hair transplant. For wider background on caring for the area between sessions, see our guide to a nourished scalp.
A standard course runs to four sessions spaced two weeks apart. The exact number is set by the treating practitioner after looking at the condition of the hair and scalp, so individual plans can be shorter or longer than this.
How much product is in one unit? Each unit holds 1 ml.
What is the hyaluronic acid concentration? The formula contains 0.7% cross-linked hyaluronic acid.
How often are sessions usually scheduled? The usual protocol is one session every two weeks, four sessions in total.
