Key Ingredients & Why They Matter

1. Biotin

Biotin helps strengthen hair strands from the root. With continued use, users often experience reduced breakage and thicker-looking hair.

2. Saw Palmetto Berry Extract

A natural DHT blocker that may support healthier hair growth and reduce shedding.

3. Coconut Oil

Moisturizes without weighing hair down. Helps maintain softness and shine.

4. Loquat Fruit Extract

Rich in vitamins and minerals that nourish the scalp and encourage healthier-looking strands.

5. Amino Acids + Vitamin B5

Enhance elasticity, hydration, and manageability.

This combination creates a balance of cleansing, strengthening, and nourishing effects—making it ideal for fine, thinning, or damaged hair.

How It Performs: Real-World Results

✨ Thickening Effect

After the first wash, many users notice that their hair feels fuller and has more body. The shampoo gently lifts the roots, giving the impression of lighter, more awake hair.

✨ Softness & Shine

Despite being a thickening shampoo, it doesn’t leave hair dry or stiff. Instead, it creates a clean, airy volume paired with natural shine.

✨ Reduced Breakage Over Time

The biotin and amino acids work over time to reduce split ends and breakage. With consistent use, hair feels stronger during brushing and styling.

✨ Scalp Health Improvement

The formula is gentle and non-stripping. Users with oily roots and dry ends benefit especially from its balancing effect.

✨ Works Well With Styling Products

The shampoo pairs beautifully with heat styling or blowouts. It provides a great base for volume-boosting mousses, sprays, or rollers.

Who Should Use This Shampoo?

The R+Co Dallas shampoo works best for:

• Fine or thinning hair

• Flat hair with no natural volume

• Limp, lifeless strands

• Hair that breaks easily

• Anyone wanting a fuller, thicker appearance

• Users looking for vegan + cruelty-free formulas

It may not be ideal for those with extremely curly or coily hair seeking intense hydration, as it is more of a strengthening and volumizing formula.

---

How to Use It for Best Results

1. Wet hair thoroughly with warm water.

2. Apply a small amount (a little goes a long way).

3. Massage into the scalp for 30–60 seconds to activate the thickening ingredients.

4. Rinse thoroughly.

5. Follow with R+Co Dallas Thickening Conditioner for maximum fullness.

For best results, use regularly for at least 2–4 weeks.

What I Loved Most

Clean, Fresh Scent

Subtle and modern — not overpowering.

Vegan & Safe Ingredients

No harsh chemicals, no sulfates, and never tested on animals.

Salon-Quality Results

You can feel the difference in smoothness, shine, and overall hair density.

Potential Drawbacks

• It is more pricey compared to drugstore thickening shampoos.

• Results vary — those with extremely thick or coarse hair may not notice a dramatic change.

• Works best when paired with the conditioner or styling products from the Dallas line.
