Questions, answered straight.

How the routine works, what things cost, and what happens with your money. If your question isn't here, a real human will answer at contact@herlayra.com or +1 833 660-3999.

Using the routine

How do I apply the Scalp Serum?

Part your hair to find the scalp, mist the serum straight onto the scalp โ€” not down the lengths โ€” then massage for ten to fifteen seconds. Start light: a little goes a long way, and a few days of use will tell you the right amount for your scalp. It's a water-light leave-on mist, so there's nothing to rinse.

Do I use it every day, or only on wash days?

Both. The Scalp Serum is the daily anchor โ€” it works on wash days and non-wash days, on dry or towel-dried hair. Shampoo and Conditioner are for wash days: cleanse the scalp, condition the lengths. Three steps, each doing its own job.

How long does one bottle last?

The serum is 79 ml, and the honest answer is: it depends on how you use it. Coverage varies with your parting, your hair, and how light you spray โ€” which is why we teach start light. We won't publish a "lasts X days" figure until we've measured it in real use; built to prove, not just promise. If you're going through it faster than feels right, write to us and we'll help you adjust your amount.

What does it smell like?

A distinct herbal scent โ€” and we'll be straight with you: opinions split. Some early reviewers loved it; some found it strong. Scent is personal, so we describe it honestly and let you decide.

Should I patch test? What if my scalp feels irritated?

If your skin is sensitive, patch test first: mist once onto your inner forearm or behind your ear and wait 24 hours. If you ever notice stinging, redness or irritation, stop using the product and tell us at contact@herlayra.com โ€” we take every report seriously and we'll look after you, including your refund options. HERLAYRA is a cosmetic for external use only; avoid contact with eyes, and for medical concerns, consult a qualified clinician.

Choosing your kit

Which kit should I start with?

Core, for most people. It's our recommended first routine: two Scalp Serums plus mini Shampoo and Conditioner, so you start with the daily scalp step and preview all three steps before committing to full sizes. Prefer to test the serum alone first? That's exactly what Essential is for.

What's inside each kit?
  • Essential โ€” $39. One Scalp Serum (79 ml). Just the scalp step. Ships at our flat $5 rate (orders under $40).
  • Core โ€” $69. Two Scalp Serums plus mini Shampoo & Conditioner. Our recommended first routine. Free US shipping.
  • Complete โ€” $99. Two Scalp Serums plus full-size Shampoo and Conditioner. The full routine from day one. Free US shipping.

Guarantee & returns

What's the difference between the 90-day guarantee and returns?

They're two separate protections. Returns: any unopened, unused product can be returned within 30 days. The 90-Day Guarantee โ€” "Love it in 90 days โ€” or your money back" โ€” covers your first one-time order on HERLAYRA.com โ€” Essential, Core, or Complete โ€” so you can actually use the routine and still be protected. To be clear: the guarantee is a promise about your money, not a promise of a specific hair result. The guarantee page has exactly how it works.

How do I make a return or a guarantee claim?

Email contact@herlayra.com with your order number and a line about what happened โ€” that's it. A real human replies with next steps. Guarantee claims are handled through your original order, so there's nothing to dig up beyond the order number.

How can I pay?

Checkout is handled securely by Shopify Payments โ€” all major credit and debit cards, plus Shop Pay, Apple Pay and Google Pay.
