Why Allpa is Different
One Ingredient
Pure castor oil. No fillers, no carrier blends, no synthetic fragrance. What's on the label is what's in the bottle.
Hexane-Free
Cold-pressed without chemical solvents. Most conventional castor oils use hexane for extraction. Ours never does.

Your bottle is filled the day it ships, not sitting on a shelf losing potency for months.

Thicker than most oils by design. You can feel the quality the moment it hits your fingertips. A little goes a long way.

"The castor oil has really done wonders on the hair fall. When I use the castor I really don't have any hair falling out. My hair used to shed so much."— Colleen C.
"My rapidly thinning eyebrows have really started growing. They're filling in and look so much better after only a month. I apply a small amount using a spooly every night."— Denise H.
"This is pretty thick and I was worried about how it would wash out, but there was no issue. It leaves my hair feeling very soft and my scalp has never felt better."— Kelsey D.
"I've been using the castor hair oil for about a month now. The difference is subtle but my hair definitely feels healthier and even a bit thicker. Recommend for giving thin hair more volume!"— Habiba W.
"Used on my eye lashes and can't believe how much longer they are becoming."— Dorothy M.
Behind the Formula
Why It Works
01
Supports Fuller-Looking Hair
If you're finding more hair on your brush than you'd like, you're not alone. Castor oil is rich in ricinoleic acid, a fatty acid that makes up the majority of the oil and has been evaluated for its hair conditioning and protective coating properties (Tessema SS, 2019, American Journal of Applied Chemistry). It coats each strand, helping hair look and feel thicker over time with consistent use.
02
Brows and Lashes Look Fuller
Sparse brows from over-plucking or age-related thinning? A single drop on a clean spoolie before bed is all it takes. Customers consistently report their brows and lashes look noticeably fuller with nightly application. The oil's thick consistency actually helps here: it stays where you put it and conditions overnight without running.
03
Deep Scalp Conditioning
A dry, uncomfortable scalp makes everything worse. Research suggests castor oil's fatty acid profile helps it form a natural barrier that locks in moisture and helps your scalp feel nourished, not stripped. Apply a few drops, massage in, and let it work overnight. Your scalp should start feeling more comfortable within the first few uses.
04
Cold-Pressed Purity You Can Trust
Most conventional castor oils are extracted with hexane, a chemical solvent that's faster but can leave residue. Ours is cold-pressed, preserving the oil's natural fatty acid profile without any chemical processing. That thick, golden oil in the bottle is exactly what pure castor oil should look and feel like.

How to Use
For Best Results
01
Warm a Few Drops
Place 3-5 drops in your palms and rub them together for a few seconds to warm the oil.
Why So Few Drops? This oil is thick and concentrated. A little goes a long way. Start small and add more if needed.
02
Massage Into Your Scalp
Work the oil into targeted areas with your fingertips using small circular motions. Focus on thinning spots or dry patches.
What You'll Notice The oil feels rich and creamy as you work it in. That thickness is pure castor, nothing diluted.
03
Leave In Overnight
Cover your pillow with a towel and let the oil absorb while you sleep. It conditions your scalp and strands as you rest.
04
Wash Out in the Morning
Shampoo as normal. The oil washes out completely, leaving your hair feeling soft and conditioned, not greasy.
For Brows and Lashes Dip a clean spoolie in the oil and apply a thin coat to brows or lashes before bed. It absorbs overnight.
* Always patch test first. Avoid contact with eyes. If irritation occurs, stop use.

Frequently Asked Questions
Common questions about our Castor Hair Oil.
Your hair should feel softer and more conditioned within the first few uses. Visible changes like fuller-looking hair or less shedding develop over weeks of consistent use. Most customers who use it 2-3 times a week for 6-8 weeks report the best results. Not everyone sees the same changes, and that's okay.
They do different things. Castor oil is great for targeted areas like thinning spots, brows, and lashes. Rosemary oil works well across the full scalp. Many of our customers use both and say the combination works better than either alone. You can alternate nights or mix a few drops of each.
It works well on all hair types, from fine to coarse to curly. For fine hair, start with fewer drops and focus on the scalp, not the lengths. One note: if you have seborrheic dermatitis, castor oil may not be the best fit. Our Tea Tree Oil would be a better option for that concern.
It's thicker than most oils, and that's by design. Use 3-5 drops, focus on your scalp, and shampoo normally in the morning. It washes out completely. Customers who shared this exact worry say they were surprised how clean and soft their hair felt after.
No. Castor oil is a carrier oil, not an essential oil. It's ready to use straight from the bottle on your scalp, hair, brows, lashes, or skin. No mixing, no measuring, no extra steps.
Absolutely. Dip a clean spoolie in the oil and apply a thin coat to your brows or lashes before bed. Many customers use it specifically for this and report fuller-looking results within weeks of nightly use. Just avoid getting it directly in your eyes.
Most conventional castor oils are extracted with hexane, a chemical solvent. Ours is cold-pressed without solvents, so you're getting pure castor oil with its natural properties intact. One ingredient, bottled fresh, no fillers or additives.
For hair and scalp, 2-3 times per week works well for most people. For brows and lashes, nightly application with a spoolie gives the most consistent results. Consistency matters more than quantity.
Absolutely. Many of our customers are men who use it for scalp care, thinning hair, and beard conditioning. Apply the same way: a few drops, massage in, leave overnight. It works the same regardless of who's using it.
Real talk: it doesn't work for everyone. Hair is complicated, and results depend on a lot of factors. Give it a fair shot with consistent use for at least 6-8 weeks. If it's not for you, we have a 30-day money-back guarantee. No hassle.
