How to use

Apply to damp hair after washing and towel-drying, or to dry hair as a finishing serum. For damp hair application: dispense a small amount into palm (start with a small amount and add more as needed based on hair length/thickness), rub between palms to distribute, then apply through mid-lengths and ends. Follow with blow-drying or heat styling — the serum provides heat protection during styling plus style retention benefits during drying. For dry hair application: apply to finished styling to reduce tangles, control static, add satin shine, or refresh existing styling between washes. Real critical framing: focus application on mid-lengths and ends, avoid direct application to roots for cleaner finished look. For heat styling: the 450°F/232°C heat protection allows use with hair dryers, straighteners, and curling tools per manufacturer heat rating — always use heat tools at the lowest effective temperature. Real pollution protection framing: apply as regular styling step for the daily 48-hour pollution barrier benefit per manufacturer. Store in cool dry conditions.

Who it's for

This serum is for anyone wanting premium multi-function styling serum with style retention, heat protection, colour protection, and pollution protection — particularly clients living in urban environments (pollution protection is meaningful for city-dwelling clients), clients with colour-treated hair, and anyone using heat styling regularly. We've spent years helping clients in Codsall look and feel their best, and as a working hair salon, we know clients increasingly want styling products with substantial multi-benefit positioning vs single-function alternatives — No.9 gives real practical value across multiple use cases in a single product. Real distinct positioning from No.7 Bonding Oil: serum format vs oil format gives customer choice for personal preference, hair type suitability, and specific benefit priority (No.9 has broader benefit range including pollution protection and style retention, No.7 has more focused shine/frizz-control positioning). Real coordinated Olaplex range purchase alongside other numbered products.

For adult use. Individuals with known allergies to any ingredient should check the full ingredient list before use and consult a GP or dermatologist if uncertain. Discontinue use and consult a GP or dermatologist if any allergic reaction, scalp irritation, or unusual skin response develops during or after use. Avoid contact with eyes; if contact occurs, rinse thoroughly with water. Do not apply to broken skin or open wounds on the scalp. Heat protection to 450°F/232°C per manufacturer — do not exceed this temperature when using heat styling tools, and always use heat tools at the lowest effective temperature to minimise long-term hair damage. Use small quantities — over-application causes weighed-down or greasy appearance, focus application on mid-lengths and ends rather than roots. For pregnant or breastfeeding women, check with a GP before adding new products to hair care routine. Keep out of reach of children. Store in cool dry conditions away from direct sunlight. Not for use as a general body/skin product outside intended hair styling purpose. Not intended to diagnose, treat, cure, or prevent any medical condition.
