Your scalp itches and flakes. Shampoo alone does not fix thick buildup. Bioderma Node K breaks down stubborn plaques. It stops them from coming back. French doctors use this for severe dandruff and scalp issues.

Key Benefits

  • Breaks down thick scalp plaques: Two acids dissolve buildup in 15 minutes
  • Stops itching fast: Plant extract calms nerves that trigger scratching
  • Stops flaking from coming back: Twice-monthly use keeps plaques away
  • Works on body too: Apply to elbows or knees with rough patches
  • Safe for reactive scalps: Tested on sensitive skin, no harsh irritants

Key Ingredients

Glycolic Acid: Loosens bonds that hold dead skin cells together. Thick plaques lift away easily. Salicylic Acid: Goes deep into pores to clear oil and dead skin. Stops clogs before they form. Zanthoxylum Alatum Extract: Pepper extract that calms itching by soothing nerve signals. Shea Butter: Keeps skin soft during treatment. Stops dryness and redness.

Frequently Asked Questions

Do I use this before or after shampooing?

Before. Apply to dry, unwashed scalp. Leave on 15 minutes. Rinse. Then shampoo right away with Node K Shampoo. The treatment softens plaques so shampoo removes them.

How long until I see results on stubborn flaking?

Most people see less flaking after 2 weeks. Use it twice weekly. For severe buildup, use for 3 weeks. Then switch to twice monthly to stop plaques from coming back.

Can I use this on my face for rough skin?

No. This is for scalp and body only. The acid level is too strong for your face. For face, use a gentler serum instead.

Will this sting if my scalp is already red?

It may tingle a bit. If you feel burning or see redness, use once per week instead. The plant extract helps calm your scalp over time.
