The Nutra-Therapy Shine Serum is a unique blend of lightweight superfood oils and hydrolyzed keratin protein that immediately give hair an unparelleled, vibrant shine. Unlike other serums, though, that are only topical, the Nutra-Therapy Shine Serum penetrates the hair shaft and goes to work over time to protect and repair all layers of hair's structure while smoothing the cuticle.

Perfect to use before + after styling hair to add an immediate shine and offer all-day protection against environmental aggressors, heat styling and more. Also great to ensure protection of your existing color.

FAQ 

Q: What is this serum used for?
A: This is a lightweight shine serum (leave-in hair oil) created to give hair instant shine, softness, frizz-control, and cuticle smoothing, while also repairing and protecting hair structure from environmental, heat, and styling damage. 

Q: What hair types or conditions benefit most from using it?
A: It’s ideal for dry, dull, frizzy, or heat-styled hair, or hair that has suffered chemical treatments or frequent styling. It also works well for color-treated or chemically-processed hair, helping preserve shine and manageability.

Q: What results can stylists or clients expect after using it?
A: Clients should see intense, vibrant shine, improved softness and smoothness, reduced frizz and flyaways, and more manageable, healthier-looking hair. It also helps prevent and repair split ends, and adds a protective layer against UV, heat tools, and environmental aggressors. 

Q: What are the key ingredients and why do they matter?
A: - Avocado oil — rich in essential omega fatty acids and vitamins, deeply hydrates and nourishes hair for softness and shine. 

• Hydrolyzed keratin (or silk protein/keratin blend) — helps strengthen hair structure, repair damage, and smooth the cuticle for long-lasting protection beyond surface shine. 

• Silicone-based agents (dimethiconol, phenyl trimethicone, etc.) — form a light, protective film that locks in moisture, shields hair from heat/UV, and reduces frizz. 

Q: How should it be applied for best results?
A: After styling (or before applying heat tools), rub a small amount between palms, then run through mid-lengths to ends (especially focusing on ends and any frizz-prone areas). Do not rinse out. Style as usual.
It can also be used on damp hair before blow-drying for smoother results, or on dry hair to add shine and tame flyaways throughout the day.

Q: Is this serum suitable for color-treated or chemically processed hair?
A: Yes — the formula is safe for color-treated or chemically processed hair; it helps protect color, seal the cuticle, and maintain moisture and shine even after chemical services.
