FAQs

Q What does a hair serum do?

A A good hair serum can smooth frizz, adds shine, protect from heat & also be used as a treatment to strengthen & regenerate. High-quality formulas go beyond coating the surface, they penetrate the hair shaft for lasting results. Some can also be applied to the scalp for added nourishment & rebalance.

Q Do you put hair serum on wet or dry hair?

A Most hair serums work best on clean, damp hair before styling. Some can also be used on dry hair to smooth flyaways or add shine. Always follow the product’s directions.

Q What is the difference between a serum & a hair oil?

A Both nourish & smooth, but serums focus on styling & treating concerns like frizz, shine, strength, & repair, while oils moisturize & soften. Serums are mostly used on damp hair (or some formulas can also be applied on the scalp); oils work on damp or dry hair.

Q How to use hair oil?

A Apply a small amount to mid-lengths & ends - avoid roots unless the oil is scalp-safe. Brush through for even distribution. Use on damp or dry hair as needed. Some lightweight oils can be used daily, depending on the formula & your hair’s needs.

EXPERT ADVICE

The ideal time to apply a serum is when the hair is freshly towel-dried, damp, but not dripping. That’s when the cuticle is most receptive.

Serums First, Oils Second

When layering haircare products, apply your serum before oil. Serums tend to be lighter and formulated to deliver targeted treatments, like strengthening or smoothing, while oils lock in moisture and protect against frizz.

To boost shine naturally, use a lightweight hair oil that smooths the cuticle and reflects light. Focus on the mid-lengths and ends, whether hair is damp or dry. The result: radiant hair with a silky, non-greasy finish.
