Frequently Asked Questions
Can a hair serum actually repair my split ends?
To be blunt, no product can permanently fuse a split end back together. Serums work by temporarily gluing the frayed edges of the hair shaft, which makes them look smoother and healthier. You still need a regular trim to prevent the split from traveling up the hair strand.
How often should I apply the serum?
You should apply the serum to your ends every time you wash your hair while it is still damp. You can also use a tiny amount on dry hair between washes to tame flyaways. Just be careful not to overdo it, or your hair will look weighed down.
Will these serums make my thin hair look greasy?
If you have fine hair, look for labels that say weightless or light reflecting. Apply the product only from the mid-lengths down to the very tips, avoiding your roots entirely. Starting with a single drop is the best way to avoid an oily appearance.
Is it better to apply serum on wet or dry hair?
Applying to damp hair is usually best because it helps lock in the moisture from your shower. However, applying to dry hair is a great way to hide frizz and add a quick boost of shine. Both methods are effective, so go with what fits your styling routine.
Does the fragrance in hair serum matter?
While a pleasant scent is nice, strong fragrances can sometimes irritate a sensitive scalp. If you have skin sensitivities, look for fragrance-free or naturally scented options. Otherwise, choose a scent that complements your favorite perfume without overpowering it.
