Can You Use Daily Conditioner as a Leave-In?

On Facebook, CurlTalk, and in the comments below articles, curlies often ask us: can a daily conditioner be used as a leave-in? Let’s start with intention. Why would someone use a daily conditioner (aka a rinse-out conditioner”> in this way?

  • You ran out of leave-in conditioner
  • You need to save money
  • You want to downsize your product arsenal
  • You like the hold and weight of the daily conditioner, which is commonly used for wash and go’s (for example (Mahogany Curls)

What’s the difference between daily conditioners and leave-ins?

Though you may not be aware that your hair holds an electric charge, cosmetic scientists are, and they formulate your hair products accordingly. Hair holds a negative charge, and the strength of that charge is based on the hair’s porosity. For example, dry, chemically treated, and damaged hair will have a strong negative charge. Conditioners are formulated to hold a positive charge, therefore attracting one to the other.

Can You Use Daily Conditioner as a Leave-In?

Daily conditioners hold a positive charge and act to virtually fill in the gaps and cracks in the cuticles or outer protective layer of the hair shaft. This cuticle can chip away over time from regular weathering, chemical processing, and excessive manipulation, and a conditioner is necessary to smooth and strengthen the strands by repairing its shaft.

Leave-in Conditioner

The leave-in conditioning formula is similar, as it is also a conditioner that attracts to the most negative areas of the hair. However, there are key differences. The leave-in is lightly formulated and can be used after the daily conditioning formula has been rinsed out. The leave-in conditioner is a barrier surrounding the hair shaft while the hair is prepped, detangled, and styled after cleansing and conditioning. Although it is full of conditioning agents, attempting to survive solely on a leave-in conditioner would be inadequate for regular wear and tear of the hair. It is in your best interest to use products as they were formulated for the best results.

On the other hand, there may be times when you are out of your leave-in conditioner and opt not to rinse out your regular conditioner. If that is the case, let’s hear from an expert. We asked a representative from Miss Jessie’s, whether their Miss Jessie’s Crème De La Crème Conditioner could be used as a leave-in rather than the Miss Jessie’s Leave-in Condish, and they said that “Yes, you may use our regular conditioner as a leave-in as an alternative if you don’t have a leave-in, however, make sure to use less than the amount you would if you were rinsing it out to avoid buildup on the hair and scalp, causing it to flake and affect the outcome of your styling results.”

Miss Jessie’s products have lightweight formulas, so in their case, this may work for you. As I Am is another hair care line that approves leaving in its As I Am Long & Luxe Pomegranate & Passion Fruit Conditioner Strengthening and Hydrating Treatment. But we would not recommend using daily conditioners with heavier consistencies as your leave-in.

Beware of buildup

A buildup of product residue on the hair shaft can impact your hair’s ability to be enhanced by other hair products (i.e., styling products”> because the formula of a daily conditioner is stronger than that of a leave-in conditioner. Unfortunately, too much of a good thing can be a bad thing. So what makes DevaCurl and Miss Jessie’s conditioners risk-free? It is the absence of non-water soluble silicones. Use this guide when choosing your conditioner to prevent product buildup by Audrey Davis Sivasothy, author of The Science of Black Hair: A Comprehensive Guide to Textured Hair.
