CP-1 3 Seconds Hair Fill-Up Ampoule

It is a single-use Korean hair treatment for dry, damaged hair. You mix the liquid 1:1 with water, where it turns creamy, then work it through the mid-lengths and ends. Silk, keratin and ceramides leave hair feeling softer and looking glossier and smoother, all in one quick treatment.

Mix the ampoule 1:1 with water until it becomes creamy. Apply to clean, towel-dried hair, focusing on the mid-lengths and ends and avoiding the roots and scalp. Distribute evenly along the length, leave on for the time stated on the pack, then rinse thoroughly. Use as a weekly treatment.

"Fill-up" refers to the treatment coating dry, damaged lengths with proteins like silk and keratin, so the hair surface feels smoother and looks fuller and glossier. It cares for the appearance of rough, worn ends rather than changing the hair itself, and works best used consistently once a week.

Each ampoule is a single-use sachet designed for one full treatment. One is enough for most hair lengths; very long or thick hair may prefer two. Because it is single-use, it is an easy way to try the CP-1 fill-up treatment before committing to a larger size.

The ampoule is built around hydrolyzed silk and hydrolyzed keratin, proteins known for smoothing the look of the hair surface, plus Ceramide NP, valued for conditioning dry, rough lengths. Together they leave hair feeling softer and looking glossier. The full ingredient list is shown on the product page.

Yes. It suits dry, damaged hair including colour-treated and heat-styled hair that feels rough and looks dull. Keeping the treatment on the mid-lengths and ends, away from the scalp, lets the silk and keratin coat the lengths that need it most, so hair looks smoother and feels conditioned.

No. The CP-1 3 Seconds Hair Fill-Up Ampoule is formulated without sulfates, which makes it a gentle choice for dry, damaged and colour-treated hair. As a rinse-out treatment mixed with water before use, it is designed to condition the look and feel of the lengths without stripping them.

Use it about once a week, or whenever hair feels especially dry and rough. As a richer treatment it takes the place of your usual conditioner or mask on the day you use it, rather than being layered on top. Regular weekly use keeps lengths feeling softer and looking smoother over time.
