ReKERA
ReKERA — Rebuilding the Foundation of Beautiful Hair
ReKERA is one of Little Scientist's distinctive hair care concepts, developed around the internal structure of damaged hair. The series includes products designed for professional treatment and continued care, allowing salons to build a comprehensive approach to hair care.
ReKERA
ReKERA Mist & ReKERA Emulsion
ReKERA Mist and ReKERA Emulsion are professional-grade hair care products designed to repair hair from its internal structure.
The ReKERA series helps rebuild keratin and CMC (cell membrane complex) that are lost due to coloring, perming, and aging, providing care for damaged hair at its source.
Both products feature a pleasant fruity-floral fragrance and can be used on towel-dried hair to help maintain a healthy-looking condition.
ReKERA is designed to bring salon-quality hair care into the home, combining highly functional ingredients with ease of use for effective everyday hair care.
Rather than simply repairing damage on the surface of the hair, it focuses on the underlying causes of hair damage caused by coloring, perming, and aging, with the aim of repairing and protecting the hair.

ReKERA Emulsion
The emulsion-type formula, on the other hand, contains highly concentrated repairing ingredients that remain on the hair, helping dry hair become moisturized, smooth, and more manageable.
Features
Concentrated natural repairing ingredients adhere to and remain on damaged areas, helping dry, rough hair become moisturized, smooth, and manageable. Liquid-crystal cholesterol and AEDS Keratin help restore the CMC structure.
Fragrance
A fruity-floral fragrance in which the sweet and tangy notes of nectarine and berries blend with the sweetness of honey and peach.
How to Use
- Thoroughly towel-dry the hair.
- Take an appropriate amount into the palm of your hand.
- Spread it well over your palms.
- Apply mainly to the ends of the hair.
- Dry the hair from the roots with a hair dryer.

ReKERA Mist
The mist-type formula contains penetration-enhancing ingredients that allow it to quickly reach deep into the hair shaft while also helping protect the hair from heat damage caused by blow-dryers and other heat-styling tools.
Features
Because the liquid formula is used as a fine mist, it is easy to apply evenly throughout the hair and penetrates quickly. In addition to repairing the hair from within, it also helps protect the hair from heat damage.

ReKERA Mist & ReKERA Emulsion
Technology
AEDS Keratin
AEDS Keratin (aminoethyl disulfide keratin [wool-derived]) repairs weakened keratin structures.
Nano-sized CMC and liquid-crystal cholesterol
Nano-sized CMC and liquid-crystal cholesterol. Contains five types of ceramides (EOP, NG, NP, AG, and AP), cholesterol, and 18-MEA (Quaternium-33). Liquid-crystal cholesterol helps align and bond the lamellar structure, helping maintain the CMC structure.
Collagen and Golden Silk
Collagen and Golden Silk help repair damaged areas of fine, thinning hair.
Polyamine AEE
Polyamine AEE. Inspired by the function of polyamines found in hyperthermophiles, this ingredient (arginine ethyl HCl) helps prevent heat-induced protein denaturation.
Heat-reactive collagen
Heat-reactive collagen responds to heat from hair dryers and hair irons to form a protective veil on the surface of the hair.

ReKERA Oil
From the hair you want to the hair you want to show off—one finishing drop to bring out shine and a beautiful feel.
Using ReKERA's advanced internal hair repair technology, this finishing oil is designed for those who care about shine and texture, combining hair repair with a beautiful finish.
ReKERA Oil is inspired by biomimetics, forming a liquid-crystal film on the surface of the hair to recreate its natural shine and smooth, healthy feel.
Formulated with precious natural ingredients such as kaya seed oil and tea seed oil, ReKERA Oil helps protect the hair from heat damage and UV exposure while providing both repair and a beautiful, smooth texture.
Its lightweight formula is designed to minimize stickiness after application, making it suitable for use even on color-treated hair.
Infused with the captivating Blooming Veil fragrance, ReKERA Oil incorporates advanced repair technology designed to maintain salon-quality beauty throughout the day.
Features
Inspired by the natural mechanism of sebum that helps maintain hair's shine and manageability, it supports the hair's natural condition. Rather than providing only an immediate effect after application, it gradually blends into the hair over time, helping maintain shine and manageability throughout the day.
Fragrance
Blooming Veil fragrance. It transitions from a clean, refreshing scent of lemon and bergamot to a bouquet-like sweetness, followed by a gentle sandalwood finish.
How to Use
- Take an appropriate amount into your hand.
- Spread it over your palms and work it mainly through the mid-lengths and ends of the hair.
- Finish by smoothing with a brush or lightly blow-drying.
Features
Shine and a beautiful feel
It reflects light evenly to give the hair an elegant shine and leaves it moisturized, smooth, and easy to run your fingers through.
Lightweight, non-sticky finish
After application, excess oil evaporates, leaving only the necessary ingredients to spread over the hair surface and form a protective film, resulting in a lightweight, non-sticky finish.
Manageability and protection
In addition to keeping hair manageable throughout the day, it helps protect the hair from heat damage, color fading (dye loss), UV exposure, and dryness.
Botanical Oils
Kaya seed oil
A rare oil that can only be harvested in limited areas of Japan, providing deep moisture and a soft, manageable finish to the hair.
Tea seed oil
A hand-picked, cold-pressed Japanese oil containing vitamin E and oleic acid. It provides lightweight moisture, shine, and a smooth feel.
Jojoba seed oil
With a structure similar to human sebum, it helps prevent dryness while leaving the hair with a smooth, lightweight, non-sticky finish.
Use with ReKERA Mist or ReKERA Emulsion
- Apply an appropriate amount of Mist or Emulsion.
- Use a hair dryer or hair iron.
- Take an appropriate amount of Oil into your hand and work it mainly through the ends of the hair.
- Finish by smoothing with a brush or lightly blow-drying.
Technology
Liquid-crystal film
Liquid-crystal cholesterol and natural plant oils are blended at an optimal ratio to form a highly adherent protective film (liquid-crystal film) on the hair surface, smoothing the unevenness of the cuticle and CMC and improving smoothness.
18-MEA
It mimics the hair's natural moisture barrier (18-MEA), creating a foundation that allows the oil components to adhere firmly and remain in place.
Two lactone derivatives
Two lactone derivatives react with heat from hair dryers and other heat-styling tools, bonding to and adsorbing onto amino groups in the hair, thereby enhancing the repair effect through heat.
Low-molecular-weight keratin, ceramides, and liquid-crystal cholesterol
Low-molecular-weight keratin, ceramides, and liquid-crystal cholesterol dissolve into the oil and intensively repair damaged areas, helping prevent the loss of internal hair components and hair color pigments.
Fullerene
Fullerene, with its spherical molecular structure, helps prevent dryness and supports a shiny finish.
