Frequently Asked Questions
Can I use hair serum every day?
You can, but use a very small amount. Applying too much daily can lead to product buildup, which makes hair look dull and heavy over time. Focus the product only on the mid-lengths and ends. Keep it away from your scalp to avoid an oily look.
Should I apply serum to wet or dry hair?
Applying it to damp hair is usually best for locking in moisture after a wash. This helps seal the cuticle while the hair dries. You can also use a small drop on dry hair to tame flyaways or add shine. Just be careful not to over-apply when the hair is already dry.
Will serum make my hair greasy?
Greasiness usually happens because you are using too much product or choosing a formula that is too heavy for your hair type. Start with just a pea-sized amount. Rub the serum between your palms to warm it up before distribution. This ensures an even application rather than a concentrated glob in one spot.
Does serum actually fix split ends?
No serum can permanently repair a split end. Once the hair fiber is physically frayed, only a professional trim will remove the damage. Serums act as a temporary patch, gluing the frayed edges together to make your hair look healthier. This prevents the split from traveling further up the hair shaft until your next haircut.
Can I combine serum with other styling products?
Yes, but layer them correctly. Apply your leave-in conditioner or mousse first to establish a base. Finish with your serum as the final sealing step. This locks in the previous products and provides the final smooth finish you want.
