What does your hair need?
Every concern below starts in the same place — the scalp. So the ritual is the same four steps. What changes is which step leads.
Your ritual leads with Step 01 · Shampoo
“Flat at the root. Thinner than it used to feel.”
This one starts at the scalp, so the ritual starts there too. VoluGro™ stimulates the scalp, supports follicle stem cell activity and reinforces structural proteins — building the foundation for fuller hair before anything else can work.

- Serum
- Scalp Oil
How to use it
Double cleanse every wash. Massage the scalp for a full 60 seconds.
Most people start with the Duo ($80) and add the rest as they go.
Your ritual leads with Step 02 · Conditioner
“Snapping mid-length. Split ends. Feels fragile.”
Here the strand matters more than the scalp. Hydrolyzed keratin penetrates the inner cortex to fortify from within and smooths the cuticle, sealing split ends and reducing breakage.

- Scalp Oil
How to use it
Do not skip the conditioner. Leave it 2–3 minutes, rinse cool.
Most people start with the Duo ($80) and add the rest as they go.
Your ritual leads with Step 03 · Serum
“Won't get past a certain length.”
Length is usually capped by breakage, not by growth. Reduce the breakage and length follows. The leave-in serum adds VoluGro™ and Panax Ginseng daily, between washes.

- Scalp Oil
How to use it
Daily leave-in. Expect visible change at 4–6 weeks, not 4–6 days.
Most people start with the Duo ($80) and add the rest as they go.
Your ritual leads with Step 04 · Scalp Oil
“Buildup, congestion, or an unbalanced scalp.”
A cleaner scalp lets every other active work. The weekly botanical oil treatment resets the scalp; niacinamide supports the barrier and moisture balance.

Luxurious without feeling heavy
I'm OBSESSED with this shampoo and conditioner!! They cleanse & moisturize super well. The hair doesn't feel stripped or overly soapy. The formulas feel super luxurious, like a high-end salon product. My hair is soft, shiny, and healthy for like days after.

Wow
Kind of blown away by this line. My hair is fine, dry, thin, and frizzy. But this really helped me.

What editors are saying
CEW Rising Beauty Influencer Award
"Founded by entrepreneurial sisters Alina and Inessa Vike, this shampoo and conditioner line is the science-backed and floral-scented secret behind their own dream-worthy locks. I love that the formula actually works on strengthening the hair follicles from the inside out."
CNN UNDERSCORED
"Dry hair often struggles with both moisture and breakage, and this formula addresses both by gently cleansing without stripping the scalp or strands. The shampoo leaves hair feeling soft, hydrated and noticeably fuller, which is especially important for dry hair that can easily look flat or brittle."
