How long will it take to see results?

Most moms see less shedding within a few weeks, and notice visible growth over 1–2 months. Every scalp is different, so users who stay the most consistent will see the most growth.

Will it work for my hair type?

Yes — our Hair Growth Serum is made to support healthier, fuller hair for all hair types and textures, whether your hair is fine, thick, curly, coily, straight, low-porosity, or somewhere in between.


Shedding, thinning, and weak strands don’t look the same for every woman — that’s why we focused on a formula that deeply nourishes the scalp and strengthens the roots, so it works at the source, regardless of texture or density.


Thousands of moms with different hair types have seen visible results — and in the rare case you don’t, you’re covered by our 60-day risk-free guarantee.

Will it make my hair greasy?

Nope! Our lightweight formula absorbs quickly without leaving buildup or residue. Just apply a small amount to your scalp — a little goes a long way and keeps your hair from feeling too oily.

What are the ingredients?

Our formula is made with four powerful, natural oils:

Batana Oil – to deeply nourish and repair damaged hair

Rosemary Oil – to stimulate circulation and support growth

Castor Oil – to strengthen strands and reduce breakage

Pumpkin Seed Oil – to help block DHT, a hormone known as a key cause of thinning.

This blend is formulated with safe, effective, and scientifically backed ingredients — trusted to support healthy, fuller-looking hair naturally.

Is it safe to use while breastfeeding?

Yes, our product is generally considered safe to use while breastfeeding. However, we always recommend consulting with your doctor before starting to ensure it’s right for you.

How do I use it & how long do I leave it in?

Just follow these simple steps:

1. Gently massage your scalp with a comb or your fingers for 3-5 minutes to boost circulation and absorption.

2. Apply directly to your scalp using the nozzle or to your fingers & rub it in. You can also run a small amount through your ends if they feel dry or brittle.

3. Leave it in for 1-2 hours — do not leave it in overnight as extended use can lead to buildup and irritation.

4. Shampoo and rinse it out as usual. There’s no need to double-wash unless your hair feels oily.

Consistency matters to see the most hair growth. Stick with it 2–3 times a week for best results.

How often should I use it?

Use the serum 2–3 times a week on dry hair, preferably before shampooing.

Hear from thousands of moms who reclaimed their confidence & hair by switching to Shamara.

"It got so bad I stopped letting my hair down because you could see all the thin spots. I started using this every night before bed and omg. My hair isn’t falling out like it used to and I can see so many baby hairs popping up."

— Jessie D.

“I was seriously at the point of crying every time I washed my hair. The amount that came out was insane. 3 weeks into using this oil and I swear the shedding has cut in HALF. My edges looks a lot fuller. I'm shocked."

— Michelle S.

"I’ve tried castor, rosemary, vitamins, you name it. This is the only thing that’s actually made a difference. My hair feels thicker and actually stays on when I brush it 😊 10/10."
