Mama & Kids Smooth Hair Milk [Hair Milk] (Leave-in type) 100mL 2,310 yen (tax included) / 2,100 yen (tax excluded)
'Mama & Kids Smooth Hair Milk' is a low-irritation hair milk that conditions the hair to be smoothly gliding and glossy.
While moisturizing and repairing children's thin and easily tangled hair and adults' dry hair from the core, it protects the cuticles and leads to hair that fingers run through smoothly.
Formulated with a proprietary encapsulated panthenol that repairs from the inside of the hair, and a cuticle barrier veil that prevents friction on the hair surface and conditions it smoothly. Furthermore, with a quick-drying & heat repair formula, it intensively repairs to the core of the hair utilizing the heat of the hair dryer while reducing drying time.
Also formulated with naturally derived shea butter, it gently wraps the hair and protects it from sun damage.
The birth of a hair milk that combines gentleness and repairing power, which can be used by the whole family including kids and babies, as well as those with sensitive skin and sensitive scalps.
Product Development Background
Children's hair is thinner and tangles more easily compared to adults' hair, making it prone to damage from UV rays and friction. Adults' hair suffers cuticle damage on the surface due to coloring, perms, and UV rays, causing the inside of the hair to become hollow and dry.
We aimed for a hair milk that firmly repairs hair from the core while providing peace of mind for those with sensitive skin or scalps, as well as for kids and babies with sensitive skin.
