Moo100 Moo100 Grapefruit

Grapefruit extract in hair care contributes two main benefits. The first is sensory: grapefruit has a fresh, citrus scent that carries through rinse-off and leave-on products, making it a popular fragrance-active in Korean hair care. The second is functional: grapefruit peel extract contains flavonoids and antioxidants that may help manage sebum on the scalp and provide mild antimicrobial support.

MOO100's Grapefruit line uses grapefruit as the lead active alongside a conditioning system, making the range suit scalps that tend toward oiliness or build-up. The fresh scent is noticeable but not heavy - it dissipates to a clean, light finish rather than a long-lasting fragrance, which appeals to users who want a clean-smelling result without a heavy perfume effect.

The MOO100 Grapefruit Water Shampoo comes in two sizes: 500 ml and 1500 ml (also listed as 1.5 L). Both contain the same formula - the size difference is purely about volume and value. At a standard dollop-sized application per wash, 500 ml lasts approximately two to three months of daily washing for medium-length hair. The 1500 ml format is three times the volume for around twice the price, making it the value-per-ml choice for households with multiple users or for daily washers with longer hair.

The 1500 ml pump-bottle format is common in Korean hair salons and homes where refilling smaller dispensers from a large bottle is standard practice. The shampoo uses mild surfactants suited to daily washing without stripping the scalp's natural moisture balance.

MOO100 offers two treatment textures: the Grapefruit Water Treatment (300 ml) and the Grapefruit Butter Treatment (500 ml and 1500 ml). These represent different conditioner weights for different hair types and concerns.

The Water Treatment has a lighter texture similar to a rinse-off conditioner. It detangles and adds basic softness without weighing hair down, which makes it suitable for fine or normal-weight hair that goes limp with heavy conditioning products. The Butter Treatment is richer and denser, suited to dry, coarse, or chemically treated hair that needs more intensive nourishment. Both are rinse-off treatments applied after shampooing, left on for two to three minutes, then rinsed thoroughly.

The LPP Grapefruit Butter Treatment (500 ml) adds LPP (liquid protein polymer) technology to the standard Butter Treatment base. LPP treatments are a Korean hair care category designed for damaged or over-processed hair - the protein polymer fills micro-cracks in the hair shaft and temporarily strengthens the strand, reducing breakage and improving elasticity.

This makes the LPP version the targeted treatment for hair that has been bleached, colour-treated, permed, or heat-styled frequently. Use it in place of the standard Butter Treatment on wash days when hair feels particularly brittle or dry, or use it as the permanent replacement for the standard version if your hair is consistently damaged. The 500 ml size provides approximately three to four months of twice-weekly use.

Wash routine: wet hair thoroughly, apply one to two pumps of Grapefruit Water Shampoo to the scalp and roots, lather and work down to the ends, rinse completely. Follow with the Water Treatment or Butter Treatment applied from mid-length to ends - avoid applying treatment directly to the scalp to prevent build-up. Leave on for two to three minutes, then rinse thoroughly with cool water to seal the cuticle.

For very dry or damaged hair, apply the Butter Treatment or LPP Butter Treatment to towel-dried hair and leave on for five minutes before rinsing. The extended contact time allows more conditioning agents to penetrate the hair shaft. Avoid using treatment on the scalp if you have an oily scalp - conditioning agents at the roots contribute to greasiness and can clog follicles.

Fine or oily hair: the Grapefruit Water Shampoo's mild formula is ideal for daily washing without over-stripping, and the Water Treatment (300 ml) provides enough conditioning without weighing fine hair down. Avoid the Butter Treatment on the scalp - apply only from the ears down.

Normal to medium-density hair: the standard Butter Treatment (500 ml) provides sufficient nourishment for twice-weekly conditioning. Chemically treated, bleached, or coarse hair: the LPP Grapefruit Butter Treatment (500 ml) is the appropriate step - the protein polymer helps rebuild the hair shaft weakened by chemical processing. All hair types benefit from the cool-rinse finish after treatment to lock down the cuticle and add shine.

For a household with one person washing hair daily, the 500 ml shampoo lasts two to three months. Two people using it daily will need the 1500 ml format for comparable value. The 1500 ml Butter Treatment is similarly sized for multi-person use or for a single heavy user - it is not common for single users to get through 1500 ml of treatment before the six-to-twelve month shelf life on an opened bottle expires.

The 300 ml Water Treatment is the smallest and most conservative commitment in the range, suitable for testing whether lighter conditioner is enough for your hair or whether you need the richer Butter version. First-time buyers can start with the 500 ml shampoo and 300 ml Water Treatment together to test the grapefruit scent profile and texture before buying the larger value sizes.
