Metrin O & O Hair Care Duo

Product Overview 

A gentle shampoo for hair that needs freshness, softness, and lift 

Metrin O&O Volumizing Hair Shampoo is designed to cleanse away daily buildup while helping preserve the hair and scalp’s natural moisture balance. 

Instead of leaving hair feeling harshly stripped, it helps create a clean, refreshed foundation for softness, body, shine, and easier styling. 

Used on its own, it is a gentle shampoo for regular cleansing. Used with Metrin O&O Repairing Hair Conditioner, it becomes part of a simple two-step hair-care routine for soft, radiant, full-looking hair.  

Why It Works 

Clean hair, without the heavy feeling 

Hair can quickly look flat when it is weighed down by buildup, styling products, excess oil, or environmental residue. Metrin O&O Volumizing Hair Shampoo helps cleanse the hair and scalp so hair can feel lighter, fresher, and easier to style. 

Softness and shine, not dryness 

The formula is designed to cleanse gently while helping hair maintain a soft, healthy-looking finish. It is suitable for regular use and can be used by customers with color-treated or chemically treated hair. 

Made to pair with conditioner 

For best results, follow with Metrin O&O Repairing Hair Conditioner to help detangle, hydrate, smooth, and soften the hair.
