Frequently Asked Questions
Should I apply hair serum to my roots or my ends?
You should almost always focus on the ends of your hair. Applying serum to the roots can make them look greasy and weigh down your volume. Start by applying the product from the mid-lengths downward. Work any remaining residue on your palms into the top layers only if you have stubborn flyaways.
Can I use hair serum every single day?
You can use these products daily, but keep the amount very small. Using too much serum over several days will lead to a heavy buildup that makes your hair appear dull. If you notice your hair feeling sticky, skip a day or use a clarifying shampoo to reset. Your hair should remain soft, not stiff, after application.
Is there a difference between hair oil and hair serum?
While the terms are often used interchangeably, a serum is typically a blend of silicones and conditioning agents designed for smoothing. A pure hair oil is often thicker and intended for deep nourishment or scalp treatments. Think of a serum as a finishing tool for style and shine. Oils act more like a deep treatment to address long-term dryness.
Will hair serum make my fine hair look flat?
It might, if you choose a formula that is too heavy or use a generous amount. To keep your volume, look for serums labeled as lightweight or volumizing. Apply the serum only to the bottom two inches of your hair. This keeps the weight off your roots and maintains a bouncy, healthy look.
Does hair serum help with split ends?
Serums provide a temporary fix by sealing the frayed edges of the hair shaft. They make split ends look smoother and feel softer for the duration of the day. However, nothing can truly heal a split end once the hair has physically separated. The only way to remove them is to get a professional trim at a salon.
