Deep Conditioning: How Much Is Too Much? (and What’s Just Right)

A few weeks ago, we got a message from a customer named Jen. She had just bought a jar of our Honey and Irish Moss Deep Conditioner and was really looking forward to giving it a try. However, in this same message thread, she admitted something that many of us at this time still don’t know the answer to either. She told us that while she deep conditioned her hair many times in the past, she still didn’t know how often she should actually do it. 

At some point, each of us stood in the shower wondering, “Am I deep conditioning too much? Or not enough?” The truth is, the question of how often you should deep condition your hair does not have one size fits all answer. It depends on a number of factors like your hair type, the porosity of your hair and whether your strands have been through heat, color or even chemical treatments. So we’ve decided to share with all of you, exactly what we shared with Jen, with the hope of answering this question we all had at some point.

Why Deep Conditioning Matters

Before we get into the frequency at which we should deep condition our hair, lets understand why deep conditioning matters because lot of folks still don’t understand why.

 Deep conditioning does the following to your hair:
•    Rebuilds strength: Tiny proteins slip inside the hair shaft and patch up weak spots.
•    Locks in moisture: Rich butters and oils smooth down frizz, seal in hydration, and bring back shine.
•    Targets damage automatically: Damaged hair attracts more conditioner, so it naturally gets extra love where it’s needed most.
•    Translation? Your hair feels softer, looks shinier, and is more resistant to breakage.

How Often to Deep Condition – By Hair Type

Type 1 Hair (Straight and Fine) – Once every 3-4 weeks

Persons with type 1 hair, as long as its in a relatively healthy condition, don’t need to deep condition that often. About once a month is fine. With type 1 hair, the natural oils and additional protective products travel down the strands very easily and provide great lubrication and protection. If you deep condition this hair type to often, it can weigh down the hair very quickly and cause unnecessary product build up. This can make the hair look super greasy and make it more difficult to style. 

Type 2 Hair (Wavy) – Once every 2 weeks

As persons with type 2 hair have a bit more curls than those with type one hair, they should deep condition a couple of times per month. Similarly to persons with type 1 hair, unless your hair is badly damaged, you shouldn’t deep condition more than this. You risk weighing down your beautiful wavy strands, making them lose their bounce and risk product build up as well. A couple times a month should be fine to maintain your hair’s volume, help to reduce frizz and keep your waves smooth. 

Types 3 and 4 (Coily or Kinky) – Once a week

Due to the curls and coils of types 3 and 4 hair being much tighter than types 1 and 2 hair, the natural oils have a hard time making its way down the hair strand. This impairment causes types 3 and 4 hair to not receive a lot of natural lubrication and this tends to result in dry hair that is susceptible to breakage. That’s why persons with these hair types tend to use a lot more moisturizing products than types 1 and 2 hair. 
Deep conditioning types 3 and 4 hair about once a week not only helps to keep moisture in the hair, but it also helps to repair any damage that has begun to happen. As we’ve stated before, damaged hair attracts more of the deep conditioner so it will naturally get the extra love that it needs. 

Porosity Matters!

Your hair type isn’t the only factor to take into consideration when determining how frequently you should deep condition your hair. Your hair’s porosity also plays a major role.

Low Porosity Hair

If you have low porosity hair, you shouldn’t deep condition too often. Your cuticles are tightly bound and tend to lay very flat. This means that your hair strand will not easily absorb the conditioner and most of it will remain on the surface of the hair  and will lead to product buildup.
When deep conditioning low porosity hair, its important to apply heat to the hair in order to open up the cuticles to be able to absorb the conditioner. Using a steam cap can easily achieve this.

Medium Porosity Hair

Persons with medium porosity hair tend to have it the easiest. Your hair’s balanced cuticle structure allows for moisture to be easily absorbed without excessive retention issues. Maintaining the standard deep conditioning schedule based on your hair type will work best for a persons with medium porosity hair.

High Porosity Hair

The opposite of low porosity hair, high porosity hair has cuticles that are lifted up along the hair strand. This allows conditioner to be absorbed very quickly and easily, but the hair loses moisture just as quickly as well. Persons with high porosity hair will need to deep condition often, about once a week. In some cases, especially for persons with type 4 hair (4C in particular), they may need to deep condition up to twice a week as their hair struggles to hold moisture. 
Its also recommended that if you do have high porosity hair, try to get a deep conditioner that will provide a strong external seal and that will help keep moisture in the hair for longer. 

Don’t Overdo It

As beneficial as it is to deep condition your hair, its important that you don’t overdo it. There are definite draw backs to this.
Hygral Fatigue and Moisture Overload
This happens when your hair takes in and releases too much water too often. This constant swelling and shrinking weakens the strands, making them feel soft, stretchy, dull, frizzy, and more likely to break.
It usually affects people with high-porosity or chemically damaged hair, since their cuticles are already lifted and let water in too easily.
To prevent it, avoid over-moisturizing, use products that seal in moisture.

Scalp Issues and Breakouts

Sometimes, the rich oils and ingredients in conditioners or styling products can slide off your hair and onto your skin, especially around your forehead, hairline or neck. When that happens, they can clog pores and cause tiny breakouts known as “acne cosmetica.”
You might notice small bumps or whiteheads near your hairline. If this keeps happening, try avoiding heavy or pore-clogging products and your skin usually clears up within a few weeks.

Deep conditioning isn’t just a “pamper step” in your hair care process. It’s the foundation of healthy, happy hair. Whether you’re rocking loose waves or tight coils, giving your strands that extra TLC makes all the difference. If you do it at the right time, your hair will forever thank you!
