The popular hair care ingredients globally mainly fall into the following categories:
Eco-friendly and Natural Polymers：
With consumers demanding more eco-friendly and gentle formulations, the trend is toward finding green alternatives to traditional petrochemical ingredients (such as polyquaterniums and silicones.
Lignin: A natural polymer extracted from wood waste. Research shows that it not only smooths damaged hair surfaces and reduces combing resistance but also has antibacterial properties and UV protection, and it is highly biodegradable.
Chitosan: A natural material derived from crustacean shells, insect exoskeletons, or fungal cell walls. With three major functions-antibacterial, repairing the scalp barrier, and regulating micro-ecology-it has become a popular ingredient for international brands competing in the high-end market.
Popular Plant Extracts and Natural Oils：
Natural plant ingredients are favored by major brands, performing well in hair loss prevention, repair, and oil control/dandruff relief:
Ginger root extract: Known for its soothing, anti-inflammatory, antioxidant, and hair growth-promoting effects, it is widely used in anti-hair loss products to address hair loss at the root.
Polygonum multiflorum (Fo-Ti) root extract: Effective in preventing hair loss and darkening hair, with a long history of use in hair care products, commonly used to strengthen hair and condition the scalp.
Coconut oil: Rich in fatty acids (such as lauric acid), it improves hair smoothness and manageability, providing a silky feel without weighing hair down, making it a popular natural alternative to silicone.
Argan oil and olive oil: Rich in unsaturated fatty acids, vitamin E, and antioxidants like squalene, they provide deep nourishment, prevent moisture loss, and repair damaged hair.
Rosemary essential oil: High in cineole, it offers a refreshing sensory experience and is often used to stimulate hair regrowth, massage the scalp, and enhance the formulation's sensory appeal.
High-efficiency Repair and Functional Ingredients：
To address hair damage caused by frequent styling and dyeing, the following ingredients are highly regarded for repair and scalp conditioning:
Hydrolyzed keratin: Can precisely fill in lost keratin in hair, strengthening strands to prevent breakage, making it a core ingredient for repairing damaged hair.
Panthenol (Provitamin B5): Offers excellent moisturizing and repairing effects, coats hair strands, enhances natural elasticity and shine, and provides a soft, smooth feel.
Citric acid: Extracted from lemons, it is a type of fruit acid. It excels in oil control and dandruff removal, effectively cleansing scalp debris and regulating sebum production.
Piroctone olamine: Known as the 'gentle anti-dandruff rising star,' its advantages of high antibacterial efficiency, safety, and mildness are gradually replacing traditional dandruff-fighting agents.
Cutting-edge Biotech Ingredients：
Plant exosomes: As tiny particles carrying genetic material, proteins, and lipids, exosomes can transmit signals to other cells, triggering repair functions. Plant-derived exosome technology is being introduced into the global skincare and hair care market, shifting from surface repair to anti-aging regeneration.
Microalgae extracts: Some ingredients derived from microalgae can strengthen hair follicles from within, promoting hair growth by reducing oxidative stress and balancing cortisol, while also addressing hair loss and graying issues.
