Healthy hair starts with a healthy scalp — and a routine you can actually keep.

— The Purelix Team

Our perspective

The Purelix® Perspective on Scalp-Focused Care

Your scalp is skin. It deserves the same thoughtful, consistent care as the rest of your routine — not a heavy coat of oil applied once a week and hoped for the best.

That's why we built Purelix around consistency first. A lightweight, water-based serum you can use every single day, between wash days, without changing anything else in your life.

And it's why the applicator matters. A serum that sits on your lengths never reaches its destination. The RootDirect™ brush parts the hair and delivers the formula straight to the scalp — where your routine actually happens.

Shop Purelix® Try it 90 days risk-free

Most scalp serums never reach the scalp. Purelix® does.

Oily topicals sit on your lengths because they were never designed to get past them. The RootDirect™ brush parts the hair and places a water-based formula directly on the scalp — no greasy roots, no coated strands, no extra wash day.

The difference

Why Purelix® Works Differently

Water-based serum texture — light and fast-absorbing Lightweight Water-Based Serum

Targeted Application

Direct to the scalp, along your part and thinning-looking areas.

Lightweight Water-Based Formula

No heavy oils — a texture designed for daily use.

Precision Built-In Brush

Parts the hair for you, so nothing sits on your strands.

Transparent Expectations

FAQ

Questions? We're here to help.

Will this make my hair greasy?

No. The formula is water-based and oil-free — it absorbs into the scalp in seconds and leaves no greasy film on your roots, your lengths or your pillow.

How long does one bottle last?

One 100 ml bottle is designed for about 30 days of daily use. The 3-bottle routine covers a realistic 90-day evaluation period.

When will I see results?

Cosmetic routines are judged in weeks, not days. We recommend a consistent 90-day routine before evaluating your part, temples or ponytail — which is exactly why the guarantee lasts 90 days. Individual results vary.

Is this a hair regrowth treatment?

No. Purelix is a cosmetic scalp-care product. It is not a drug and is not intended to diagnose, treat, cure or prevent any disease or medical condition, including alopecia. For medical concerns, please consult a professional.

Can I use it on dry hair or between wash days?

Yes — that is exactly what it was built for. Apply on dry or towel-dried hair, between wash days, morning or evening.

Is it suitable for sensitive scalps?

The formula is fragrance-conscious and dermatologically reviewed. As with any cosmetic, patch-test on a small area first if your scalp is reactive.

Can I use it postpartum or while breastfeeding?

Purelix is a cosmetic product, but every situation is personal. Please ask your doctor or midwife before adding any new product during pregnancy, postpartum or breastfeeding.

Is there a subscription?

No — never. Every order is a one-time purchase. No recurring charges, no cancellation maze.

What if it doesn't work for me?

The 90-day guarantee applies to used product — opened bottles included. If after 90 days the routine doesn't fit your life, contact us and we make it right.

Where is it made?

The serum is formulated and filled in a cosmetic-grade, GMP-certified facility. The full INCI list is published before launch and printed on the packaging.

Can I use it with other styling products?

Yes. Apply the serum first, directly on the scalp, let it absorb for a minute, then style as usual.

Do I need to rinse it out?

No. It is a leave-in serum — apply, distribute, and move on with your day.

What does it feel like on the scalp?

Light and fresh, with a gentle cooling sensation from menthol on application. No stickiness, no heaviness.

How is this different from rosemary oil?

Oils coat the hair and sit on top of it. Purelix is water-based and is delivered straight to the scalp with a brush applicator — the routine happens at the root, not on your lengths.

Haven't seen big changes yet at week 4, but the texture is great and I can actually stay consistent. That's new for me.

Megan K. Verified Buyer

My ponytail looks a bit fuller in my progress photos at week 10. Same light, same angle — the guide they send is genuinely useful.

Hannah D. Verified Buyer

Bought the 3-bottle pack because the guarantee is on used product, not sealed boxes. Respect for that.

Finally a scalp product that doesn't turn my fine hair into an oil slick. My stylist asked what changed.

Sofia L. Verified Buyer

Two bottles in. What I notice most: my part doesn't catch the light the same way in photos. Subtle, but real to me.

Chloe V. Verified Buyer

Ordered the 3-bottle pack after reading every word on the page. No hype, clear INCI, honest timelines. The routine itself takes a minute.
