Cleanse the scalp with Rosemary Shampoo

Nourish with 9-in-1 Hair Oil

Cleanse, then leave in botanical nourishment

A two-step cleanse-and-nourish set with one Rosemary Shampoo and one 9-in-1 Hair Oil. Shampoo refreshes the scalp before a few drops of leave-in oil bring softness, shine and care to your scalp and lengths.

The oil combines castor, coconut, rosemary, jojoba, peppermint, ginger, vitamin E and grapeseed oils with real peppermint leaves. Conditioner is a separate optional addition and is not included.

  • Scalp-focused cleansing: Rosemary Shampoo washes away everyday buildup for a fresh-feeling start.

    Botanical nourishment: 9-in-1 Hair Oil helps soften dry-feeling hair and adds a smooth, healthy-looking shine.

    Flexible care: Use shampoo on wash days and adjust the leave-in oil to your scalp, texture and styling routine.

Choose this pair when you want both a scalp cleanse and a leave-in oil, or already have a conditioner you enjoy. It suits different hair textures and genders; adjust the amount to your needs.

If you also need conditioning for softness and detangling, add a conditioner separately or explore the complete three-step routine.

1. Massage Rosemary Shampoo into thoroughly wet hair and scalp for 1–2 minutes, then rinse well.

2. Apply a few drops of 9-in-1 Hair Oil to your scalp or lengths and massage gently. Leave in and style as usual.

Start with a small amount, especially on fine hair. Use shampoo on wash days and oil daily or several times a week as your hair needs.

WHY WE STARTED

I started OilnGlow in 2021,for the natural ingredient products I couldn’t find

For years, I dealt with hair breakage that seemed to get worse as years went by. Then came eczema flare-ups, irritation, and the itching... don’t get me started.
I started paying closer attention to ingredient labels and realized how difficult it was to find simple, nature-focused products without long lists of ingredients I didn’t recognize. I got tired of searching. So I started buying individual carrier oils and creating my own blends at home. I made them for myself first. Then family, friends. and friends of friends started wanting some.
And the rest is OilnGlow.
What began as a personal search for something simpler became a promise: to create thoughtful products centered around clean, natural ingredients wherever possible without making skincare and haircare more complicated than they need to be.

If I can’t feel good about what’s on the ingredient list, I don’t want to put it on your shelf.

Frequently Asked Questions

This set includes one Rosemary Shampoo and one 9-in-1 Hair Oil. Conditioner and Pre-Wash Scalp Oil are available separately.

Yes. Adjust the amount of each product to your hair’s length, texture and needs. Focus shampoo on the scalp and start with just a few drops of leave-in oil.

Choose this set when you need shampoo and leave-in oil, or already have a conditioner you like. Choose the three-step routine when you also need a conditioner for softness and easier detangling.

Massage Rosemary Shampoo into thoroughly wet hair and scalp for 1–2 minutes, then rinse. Apply a few drops of 9-in-1 Hair Oil to your scalp or lengths, massage gently and leave in. Use your usual conditioner between these steps if needed.

Start with a few drops and spread them evenly. Fine hair may need less; dry-feeling lengths may benefit from a little more. Adjust the amount and frequency to how your hair feels.
