58 SCALP CARE
Scalp care innovation and wellness strategies
Amanda Jepson - Biova
Historically, hair care has been primarily focused on the outward appearances—shine, smoothness, volume, and colour protection. In the past few years there has been a growing awareness and acceptance of the critical role nutrition plays in hair health. Today, the focus is moving upstream to the scalp, the living foundation of hair growth. The global scalp-care segment grew 22%
year-on-year in 2024, driven by the skinification of the hair care market and consumer demand for wellness-oriented solutions. As consumers become more ingredient-savvy and wellness-minded, they want routines that deliver visible results now, while also investing in long-term scalp health. That shift is pushing brands and formulators
to blend cosmetic performance with real biology, borrowing ideas from skin care and even clinical technologies. Three pillars are guiding this transformation.
First, peptides and amino acids are stepping into the spotlight for their ability to support follicle strength and repair, and to create a more welcoming environment for growth. Second, antioxidants are taking a bigger role
as the daily defenders against oxidative stress— from UV and pollution to heat styling and lifestyle factors—that can quietly chip away at scalp comfort and overall hair health. Third, collagen-supporting strategies—long
used in facial skin care—are proving valuable for scalp elasticity and resilience, helping preserve the ‘scaffold’ that keeps follicles well supported. Layered on top of these is a broader holistic
approach. Nutrition, stress management, and medical-grade devices, such as red-light therapy, round out the overall environment of hair care, creating integrated systems that combine topical, ingestible, and device-based approaches. The result is a category that treats scalp health
not as an afterthought but as the starting point of stronger, more resilient hair.
Peptides and amino acids: building blocks for follicle strength Peptides do more than just strengthen hair—they help set up the right conditions for growth. Some peptides improve blood flow in the scalp, so more oxygen and nutrients can reach the follicles. This becomes especially important when the scalp is under stress or as we age, because circulation naturally slows over time. Better delivery of essential nutrients often translates to better performance where it counts.

Other peptides act like calming agents for the
scalp. They help reduce low-level inflammation, which is a common - and often hidden - driver of sensitivity, discomfort, and disrupted hair cycles. By quieting this background irritation, peptides support a healthier, more stable foundation for hair to stay in its growth phase longer. Different peptide families bring different
strengths. While copper peptides are popular for their role in tissue repair and antioxidant support, which helps keep the scalp environment robust and follicles feeling more supported. Signal peptides, first celebrated in skin
care, encourage the production of collagen and other structural components that improve scalp elasticity and help hair stay anchored. Biomimetic peptides go a step further by mimicking natural growth cues; they can reinforce the proteins that secure hair and may help reduce shedding over time. Furthermore, because hair fibres themselves
are made of keratin, amino acid blends – such as cysteine, lysine and arginine - supply the raw materials for stronger hair, often paired with hydrators to maintain comfort and a smooth feel. Effective delivery is critical for peptide
performance. These actives are highly sensitive to oxidation and hydrolysis, so stability strategies matter. Encapsulation technologies help protect peptides, improve penetration, and maintain
activity over time. Formulators should also consider airless packaging to minimize oxidative stress during storage and use. Beyond stability, adjusting formulas to the
scalp’s natural pH supports both peptide integrity and skin comfort. Pairing these systems with humectants like glycerin or hyaluronic acid further enhances hydration and tolerance, creating an environment where actives can work effectively.
Antioxidants: defending against oxidative stress When we talk about oxidative stress on the scalp, we are really describing an imbalance: more ‘wear and tear’ molecules than the body can comfortably neutralize. These reactive oxygen species (ROS) can chip away at protective lipids, damage proteins, and even affect DNA inside cells that help drive hair growth. Over time, the pressure adds up—hair may
age faster, the growth phase of the hair cycle can shorten, and inflammation tends to flare more easily. Several factors of daily life contribute to this: sun exposure, pollution, heat styling, and psychological stress all put pressure and stress on the scalp. Antioxidants help make a difference by easing
that load. Vitamin C remains a cornerstone for scalp care, offering dual benefits: ROS neutralization and collagen synthesis support,
