CP-1 3 Seconds Hair Fill-Up Shampoo

It is a protein-rich Korean shampoo from CP-1, sold at Beauty Bar. It cleanses hair and scalp gently while coating dry, damaged lengths with hydrolyzed keratin, silk amino acids and argan oil, so hair feels softer and smoother straight after washing and looks glossier and healthier over time.

Apply to wet hair and massage a light lather into the scalp with your fingertips, then work it through the lengths. Rinse thoroughly with warm water and repeat if needed. Follow with a conditioner or mask through the mid-lengths and ends. Suitable for daily use.

It uses a milder surfactant blend rather than harsh sulfates as its main cleansers, which makes it a gentler everyday wash for dry, damaged and colour-treated hair. It still lathers and cleanses well, but is designed to leave lengths feeling softer and less stripped than a stronger sulfate shampoo.

Yes. Its gentle cleansing base and protein-and-oil blend make it well suited to colour-treated and heat-styled hair that feels dry and looks dull. Using it as your regular shampoo helps lengths feel smoother and look glossier, while a matching conditioner or mask adds extra slip on the ends.

The shampoo features hydrolyzed keratin and silk amino acids, proteins known for smoothing the look of the hair surface, plus argan oil, long valued for softness and shine. Alongside a gentle cleansing base, they leave dry, damaged hair feeling conditioned. The full ingredient list is shown on the product page.

Yes, it is gentle enough for daily washing. How often you shampoo is really down to your hair and scalp: every day suits finer or oilier hair, while drier hair may prefer every second or third day. Whenever you wash, follow with conditioner on the mid-lengths and ends.

The shampoo cleanses and coats the lengths, but a conditioner adds extra slip and softness on the mid-lengths and ends, which dry or damaged hair benefits from. Using the CP-1 shampoo and a conditioner together gives the smoothest result, though the shampoo still leaves hair feeling conditioned on its own.
