“Value Beyond Cleansing, a Healthy Change for the Scalp”
Lediffer Premium Deeper Shampoo goes beyond simple cleansing.
With a proprietary recipe and technology composed of over 93% natural and naturally derived ingredients, it delivers essential active ingredients deep into the scalp for fundamental improvements in scalp health.

Free from artificial colors, thickeners, silicones, and other unnecessary harmful substances, the shampoo maintains the original color of its raw materials and a light, clear texture. At first use, the foam may appear minimal, which is part of the process of breaking down impurities and harmful residues left on the scalp.
With continued use, you will experience increasingly rich lather and notice your scalp and hair regaining their natural strength.

< How to Use >
1. Wet hair and scalp thoroughly with lukewarm water.
2. Take an appropriate amount, lather onto hair and scalp, and gently massage.
3. Leave on for at least 10 minutes to allow the natural ingredients to absorb into the scalp, then rinse thoroughly with lukewarm water.
Tip: For optimal results, let the natural cleansing agents remove sebum, keratin, and impurities while soothing and nourishing ingredients absorb into the scalp and hair. Wearing a shower cap for 10–20 minutes after application enhances absorption.
