Naturally-textured hair is dry by nature; that’s why preserving as much moisture as possible is the key to hair growth and length retention. Pre-poo is the perfect way to protect the scalp’s natural oil and retain the much-needed moisture in your delicate tresses.
What is Pre-Poo?
Pre-poo is short for pre-shampoo treatment.
Pre-poo is a treatment done before the practice of shampooing, to prepare the delicate hair for the very stripping act of the shampoo.
What is the Function of Pre-Poo?
The main purpose of a pre-poo is to protect the scalps natural oil (sebum) from being washed away with the shampoo. Sulfate-free shampoos are meant to clarify the hair.
Clarifying shampoos contain Anionic surfactants, which are strong enough to remove all build-up including silicone, products, and even perspiration build-up.
Clarifying shampoos are incredibly strong and many times often too harsh for naturally textured hair. Shampoo can cleanse too deeply leaving the scalp dry, tight, and flaky.
The pre-poo will create a barrier to protect the scalp’s natural oil. After rinsing out the pre-poo with a shampoo, you will have that nice clean scalp feeling while still having your scalp’s natural sebum intact.
What Are Some Benefits of Pre-Poo?
- Increased Shine
- Hydrated scalp and hair will lead to less flaking and dandruff
- Quicker hair growth
- Lots of body and bounce
- Increased elasticity
- Primes hair for manipulation
- Preserves moisture and hair color
- Softens hair, therefore, improving manageability and health
How to Pre-Poo?
Traditionally, pre-poo is done with oil. You can use any oil of your choice. I am addicted to oil blends like Righteous Roots or my all-time favorite oil blend Thatsthatmagic. Although Tailored Beauty makes a fantastic oil blend as well, I just want to mention that since I love options. Below I have embedded how I like to do my oil pre-poo using Thatsthatmagic, this is basically the same thing as a hot oil treatment (just add a heating cap to make it a hot oil treatment).
As you can see in the video, you essentially cover your scalp and hair with the oil of your choice, cover it with either a plastic cap, shopping bag, etc to insulate the heat your scalp produces. Allow at least 15 minutes for the oil to penetrate. Since oil does not moisturize hair, you can pre-poo overnight without fear of risking hygral fatigue (over-moisturizing the hair).
Another way to pre-poo is by using conditioner instead of oil in this process. Everything is essentially the same, except for the duration. Since conditioner deposit moisture in the hair, the heat your scalp produces basically acts as a timer. It heats up the conditioner, making it even more effective much more quickly. That is why you should rinse the conditioner pre-poo out after 1-hour MAX. The longer you keep it on, the more you risk over-moisturizing your hair.
You can also use pure aloe vera as a pre-poo. The same rules apply as using conditioner. Duration is much shorter. Aloe vera is an effective moisturizer. Below I have embedded my Youtube tutorial on how I like to prepare my aloe vera pre-poo. If I have the time, I always choose aloe vera as my pre-poo option because aloe contains over 50 different minerals and nutrients the hair needs to grow and repair itself. Again, do not leave on for longer than 1 hour.
How often should I pre-poo?
Although you should pre-poo every single time you use a clarifying shampoo no matter what time of year, pre-poos are especially helpful in the winter months.
Since there is no humidity in the air (water in the air) there is nothing to moisturize your hair. In fact, winter months have some of the driest and harshest air, which eventually sucks the moisture out of your hair. Adding this simple step to your washday will save you lots of time on restyling and rewashing. It will extend the life of your wash and go!
Rule of thumb pre-poo before you shampoo, may that be once a week or once a month. Pre-poo takes at least 15 minutes to penetrate the hair but can be left on overnight. It will not cause hygral fatigue. Adding heat such as sitting under a dryer or using a microwavable cap, or even a hair steamer helps the oil penetrate.
