Description

This powerful shampoo and conditioner set helps make your hair look thicker, fuller, and healthier. The shampoo is made with biotin and prebiotics to add volume right at the roots. It’s great for all scalp types—especially if your hair is thin, dry, or damaged. It’s safe for color-treated hair, and was created by scientists and tested by dermatologists.

With ingredients like biotin, prebiotics, rosemary oil, and caffeine, it gently exfoliates, cleans your scalp, and adds moisture. This helps improve circulation and supports stronger, faster hair growth. It’s free from parabens, silicones, and sulfates. In 2024, Women’s Health Magazine named it the Best Thickening Shampoo, and it was ranked the #1 Korean hair care brand for thickening by Nielsen in 2023.

Benefits

  • Thicker, Fuller Hair: Adds volume from the roots for a fuller look.
  • Stronger Strands: Helps reduce breakage and shedding.
  • Healthier Scalp: Exfoliates and hydrates for a clean, balanced scalp.
  • Supports Hair Growth: Boosts blood flow to help stimulate growth.
  • Gentle & Safe: Free from sulfates, parabens, and silicones.
  • Great for All Hair Types: Works well on dry, damaged, oily, or color-treated hair.
  • Shinier, Softer Hair: Leaves your hair feeling smooth and looking healthy.
  • Scientifically Developed: Backed by dermatologists and real users.
  • Award-Winning: Named Best Thickening Shampoo by Women’s Health (2024).
  • Smells Amazing: Light herbal scent that feels refreshing, not overpowering.

How & Why Does It Work?

Healthy hair starts at the scalp—and that’s exactly where Dr. HairRoot goes to work.

Our shampoo + conditioner duo is powered by a blend of proven ingredients that target the root causes of thinning, shedding, and scalp imbalance:

  • Biotin: A key vitamin that helps strengthen hair strands and reduce breakage.
  • Caffeine: Boosts blood flow to the scalp, which supports healthy hair growth.
  • Encapsulated Prebiotics: Nourish your scalp’s natural microbiome and reduce irritation.
  • Rosemary Oil: A natural DHT-blocker that helps prevent hair thinning.
  • Keratin: Rebuilds damaged strands, adds smoothness, and reduces frizz.
  • Aloe Vera & Argan Oil: Hydrate the scalp and add shine without weighing hair down.
  • Salicylic Acid: Gently exfoliates to remove buildup, flakes, and excess oil.

By cleansing, exfoliating, and nourishing your scalp, Dr. HairRoot creates the perfect environment for stronger, thicker hair to grow. It’s a simple routine—but backed by serious science.

Who is it for?

Dr. HairRoot is made for anyone who wants healthier, fuller-looking hair—without the harsh chemicals or complicated routines.

It’s perfect for you if:

  • You’re noticing more shedding or thinning than usual
  • Your hair feels flat, weak, or damaged
  • You want to boost volume from the roots
  • Your scalp feels oily, flaky, or itchy
  • You’re postpartum or going through hormonal changes
  • You style your hair often and need to repair damage
