When it comes to mane & tail growth for horses, patience is a virtue.
There’s no quick fix that will give you instant results, but the good news is this DIY Mane and Tail Growth Serum can get you headed in the right direction.
Fall is the perfect time to start, giving you lots of time before you hit the show ring next summer, and it also helps combat dryness as winter approaches.
There are many factor that affect hair growth, such as genetics, nutrition, care, turnout etc. but the main purpose of this serum is to improve the health of your horse’s scalp to maximize your efforts and strengthen the existing hair.
It takes a bit of work, but really, is there anything more spectacular than a long, flowing, Friesian-inspired tail?
The key ingredient in this recipe is Castor Oil, which is loaded with hair boasting benefits.
It’s naturally anti-bacterial and anti-fugal which helps the fight against dandruff, and contains ricinoleic acid, which helps to stimulate the hair follicles, improve circulation and balance pH levels.
It’s also loaded with antioxidants that work to strengthen hair and reduce frizz. Another bonus is the price! It’s super affordable for long term use.
π² You can usually get a big 16 oz bottle on Amazon for under $18. That’s a great deal! Check the current price here.

DIY Mane and Tail Growth Serum for Horses
Materials
- 3 parts Castor Oil
- 1 part oil(s) of your choice* (suggestions below)
- *Jojoba
- *Neem
- *Olive
- *Argan
- *Coconut
- Essential Oils (optional)
Instructions
For best results, apply 2-3 times a week at the base of the tail, mane or forelock. Depending on how dry (or dirty) the hair is, you may want to lightly moisten it with water first.
I like to massage it in for a few minutes, helping to open the hair follicles and promote circulation. Castor oil is quite thick, so a little goes a long ways.
Start with just a few drops and leave it in for several hours, or overnight if possible.
I’ve found it’s usually absorbed within 12-24 hours, but if your horse is looking greasy it can be washed out (try this recipe for DIY Natural Horse Shampoo) or for a quick fix you can sprinkle corn starch over top and brush it out.
Notes
Oil Benefits:
Jojoba β great all-round oil for skin and hair, fast absorbing.
Neem β strong smell, but worth it! Anti-inflammatory and soothing.
Olive β very moisturizing and you probably have some on hand already.
Arganβ adds shine and reduces frizziness.
Coconut β Anti-bacterial, anti-fugal, anti-inflammatory, too many benefits to list! The down side is in cold climates itβs solid and would need to be melted before adding to the castor oil, making a much thicker serum.

My personal favorite is a mix of castor/jojoba/neem oil with lavender and rosemary essential oils.
Disclaimer: You should always use cation around horses, and massaging the tail area is no exception, so please be safe!
Happy grooming,
Thank you for this recipe! It really works!! My friends horse's forelock was cut off by one of the grooms taking out his braid. We have been massaging in this recipe (I also used a combo of neem and jojoba along with lavender and rosemary essential oils) for a couple of months now and his forelock has grown. Another gal in the barn asked to use some on her son's roping horse as he had no forelock and sure enough it's growing!!!!
Thanks for your feedback, I'm so glad it's working well for you π
Hi Lani, can you elaborate on the quantities (ie: drops of essential oils) you used in your blend? Thanks π
My gelding has rubbed his mane and tail off every year, has ich on his belly. This is the first time I have found anything that works. This year he has a tail and no ich on his belly. I have spent so much on products and home remedies, thank you for the great recipe.
What do you use to store this in? For personal use I store my oils in dark glass containers but I'm worried about having glass in the barn. I'm also curious about the amount of essential oils you use.Thank you!
I am using a .99 squirt bottle that you would put BBQ sauce or ketchup in. It works Wonderful!!
Can I make up a gallon of this stuff. I have a few horses. Would this get bad over a period of time?
Can you leave the serum in the horse’s mane/tail after each use or do you have to wash it out?

It should absorb into the mane/tail on it’s own, so it can be left on. Start with small amounts first, a little goes a long ways!
Could you add Geranium oil to this recipe to keep ticks out of the mane and tail? In another post, I believe you said you didn’t use Geranium oil directly on the skin but put it on fly masks, fly boots, etc. Would it be okay to apply to the skin if it was diluted?
Author
Yes, and that’s a great idea!
Please answer questions above for clarity. How many drops of each EO and how do you store this serum?

I would use just a few drops of essential oil in a small batch. You can always add more if you need it. The scent should be noticeable, but not overpowering.
Any container is fine to keep it in, but to avoid a mess, you’re best off with a narrow top and a lid (like the travel size shampoo containers from the dollar store).
Sometimes when you purchase castor oil it comes in a glass bottle with a dropper. That works great too!
I use a the application bottle after coloring my own hair. I wash it thoroughly and make the mix and store in that as I find it perfect to apply it with.
Do you massage the entire dock?
How much do you approximately use on your horses tail, should you keep your horses tail in a tail bag, and how long would you say it takes to start to see an improvement?
does it help people grow hair?
Author
Yes, it can help encourage hair growth for people too!
so, i’m mostly going to use this to grow out my horses main, she’s never really had a super long main but it’s really thick. would it work to just grow out hair or is it mostly for horses that have hair loss or injuries?
My pony had her mane roached because the trainer didnt want to bother fighting to pull it. Would this also work for her and would I need to was it out the next day or would it be fine to leave on till next application
Can I put neck sweats on after applying the oil
Is there any issue with application and sunburn?
could you put your horses tail in a tail bag to help it grow better too?
