How to Use Hair Serum the Right Way

If you're skipping serum in your hair ritual, you're missing out on the easiest way to reduce frizz, smooth roughness, and prevent everyday damage. A good serum doesn’t just style — it repairs, protects, and transforms the texture of your hair over time. But to get real results, it needs to be used the right way.

When Should You Apply Hair Serum?

After every hair wash — when your hair is freshly cleansed and slightly damp. Serum works best when applied to towel-dried hair, right before styling. That’s when it seals in hydration, smooths frizz, and helps shield against heat and humidity.

How to Use It (Step-by-Step)

1. Start with towel-dried hair
Blot gently—don’t rub. You want hair that’s damp but not dripping.

2. Take the right amount
Use the guide below to avoid over- or under-using it:

1 pump = 1 coin-size amount

3. Apply from mid-length to ends
Most serums are meant for lengths to ends — but the 2.Oh! Hair Repair Serum is potent enough to work when used just on the ends. Start with mid-length to ends if your hair is very dry or damaged. Once your strands begin to feel stronger and healthier — especially if you’re using the leave-in conditioner too — you can shift to applying it only on the ends for daily maintenance.

4. Don’t rinse
Serum is a leave-in product. Style as usual — it works whether you air dry or blow dry.

What makes the 2.Oh! Hair Repair Serum different isn’t just what it does — it’s how it does it. This formula combines three powerhouse ingredients: Active Repair Catalysts, Hydrolysed Keratin, and Argan Oil — each with a specific function, but designed to work together.

The Active Repair Catalysts, our signature complex, are designed to penetrate the hair shaft and trigger repair from within. Hydrolysed Keratin helps rebuild the protein structure inside each strand, restoring elasticity and strength. Argan Oil provides deep, lightweight nourishment that softens the cuticle and protects against moisture loss. Unlike surface-level serums, this one actively improves hair quality from the inside out — not just gloss and coat it.

The result: frizz is controlled, damage is reduced, and your hair gets better with every wash.

Just One to Try

The 2.Oh! Hair Repair Serum in Crème is lightweight, non-greasy, and highly concentrated. It restores cuticle health, helps prevent split ends, and improves the overall feel and appearance of your hair — especially when used after every wash. It’s the kind of formula that doesn’t just style — it supports hair health over time.

The Final Word

Think of this serum as your hair’s daily protection shield — smoothing, strengthening, and sealing in everything good. It’s an essential part of your healthy hair ritual.
