FAQs

What does THE HAIR SERUM do?

THE HAIR SERUM is a protective, rehydrating serum for daily use designed to help protect hair from heat, pollution, and dehydration, while improving softness, shine, manageability, and overall hair quality. It helps restore the appearance of damaged hair strands and leaves hair softer, smoother, and more supple without weighing it down.

Can I use THE HAIR SERUM every day?

Yes. THE HAIR SERUM is suitable for daily use and is designed to easily fit into your daily hair care routine.

How should I use THE HAIR SERUM?

Shake well before use. Spray onto damp or dry hair and massage gently to ensure even distribution. No need to rinse. For best results, apply mainly from the mid-lengths to the ends.

Can I use THE HAIR SERUM on both damp and dry hair?

Yes. When applied to damp hair, it acts as a heat protectant before blow-drying or styling. When applied to dry hair, it’s ideal for defining your style, smoothing your hair, controlling frizz, and adding softness and shine.

Does THE HAIR SERUM protect against heat?

Yes. One of its main benefits is that it helps protect hair from heat damage caused by styling tools such as hair dryers and flat irons.

Does THE HAIR SERUM make your hair feel heavy?

No. Its formula is designed to help lock in moisture and improve softness without weighing the hair down, so it's suitable even for hair that needs lightness and movement.

Who is THE HAIR SERUM for?

It's ideal for anyone with dry, damaged, frizzy, dehydrated, or unmanageable hair. It's also an excellent choice for those who frequently use heat styling tools and are looking for daily protection without a heavy or greasy finish.

Should I apply THE HAIR SERUM to my scalp?

No. THE HAIR SERUM is designed to protect and improve the hair shaft, so it's best to apply it from the mid-lengths to the ends, rather than directly on the scalp.

Which ROOT DEFENSE LAB products can I combine it with for a complete routine?

For a complete routine, start by using THE SCALP SCRUB and THE HAIR SHAMPOO, and then apply THE HAIR DEFENSE MASK when your hair needs extra nourishment and repair. Follow with THE HAIR SERUM as Step 3 and finish with THE HAIR MIST for additional daily protection against external aggressors. UNICLED HELMET OMEGA 5.0 also complements the routine very well, since while the helmet targets the scalp, THE HAIR SERUM helps protect, soften, and beautify the lengths.
