Frequently Asked Questions
Can I apply hair serum to my roots?
Applying serum directly to your roots will usually make your hair look greasy and weighed down, so you should focus the product from mid-lengths to the ends. The ends of your hair are the oldest and driest part of the strand, which means they need the nourishing ingredients much more than your scalp does.
Should I put serum on wet or dry hair?
Most serums work best when applied to damp, towel-dried hair because the moisture helps lock the product into the cuticle as it dries. You can also use a tiny amount on completely dry hair as a final finishing touch to tame flyaways and add instant shine.
Will hair serum make my fine hair flat?
Heavy oils will definitely flatten fine hair, but you can avoid this by choosing a silicone-based fluid or a sprayable serum specifically formulated for fine textures. Always start with half the recommended amount, warming the product between your palms before gently pressing it into the lower half of your hair.
How often should I use a hair serum?
You can safely use a hydrating serum every single day if your hair is extremely dry, coarse, or regularly exposed to heat styling. If your hair is finer or prone to product buildup, limit your applications to two or three times a week right after washing.
Does hair serum actually repair split ends?
No topical product can permanently glue a split end back together, but serums temporarily seal frayed cuticles to make your hair look sleek and healthy until your next haircut. Think of serum as a cosmetic bandage that prevents further splitting by shielding your ends from friction and environmental stress.
