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 have wondered too…she wasn’t quite sure how often she should actually deep condition her hair.
Her question got us thinking. How many of us really know the science behind deep conditioning? At some point, we’ve all stood in the shower wondering, “Am I deep conditioning too much? Or not enough?” The truth is, there’s no one-size-fits-all answer. It depends on your hair type, porosity, and whether your strands have been exposed to heat, colour, or chemical treatments.
So, we’re sharing the same advice we gave Jen and hopefully, it helps you find your perfect deep conditioning rhythm too!
Why Deep Conditioning Matters
- 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 becomes more resistant to breakage.
How Often to Deep Condition – By Hair Type
**Type 1 Hair (Straight and Fine)** – Once every 3–4 weeks
If your hair is straight and relatively healthy, deep conditioning once a month is usually enough. Natural oils travel easily down the strands, providing natural protection. Deep conditioning too often can weigh down the hair, cause buildup, and make it appear greasy or flat.
**Type 2 Hair (Wavy)** – Once every 2 weeks
If you have wavy hair, aim for a deep conditioning session about twice a month. This helps maintain your waves’ bounce and shine while minimizing frizz. More frequent treatments aren’t necessary unless your hair is damaged, as too much moisture can lead to buildup and limp strands.
**Types 3 and 4 (Curly, Coily, or Kinky)** – Once a week
Curly and coily hair textures naturally struggle to distribute oils from root to tip, making them prone to dryness. Deep conditioning weekly helps restore moisture, repair damage, and strengthen your curls. Damaged areas tend to attract more of the conditioner automatically, so your hair gets extra care where it needs it most.
Porosity Matters!
Your hair type isn’t the only factor to consider when deciding how often to deep condition. Your hair’s porosity (how easily it absorbs and holds moisture) also plays a big role.
**Low Porosity Hair**
If you have low porosity hair, you shouldn’t deep condition too often. The cuticles are tightly closed, so products tend to sit on the surface rather than absorb in. Apply gentle heat or use a steam cap to help lift the cuticles and improve absorption when you do deep condition.
**Medium Porosity Hair**
You’ve got it the easiest! Your cuticle structure allows moisture to enter and stay balanced. Following the standard deep conditioning schedule based on your hair type usually works perfectly.
**High Porosity Hair**
High porosity hair has lifted or damaged cuticles that let moisture in, but also lets it out very quickly. You’ll benefit most from deep conditioning once a week, or even twice weekly for very dry or Type 4C hair. Look for conditioners that seal the cuticle to lock in hydration longer.
If your hair is damaged due to high heat, colouring or chemical treatments, it may be highly porous. You may need to deep condition once or twice a week until the damage has been repaired.
Don’t Overdo It
As amazing as deep conditioning is, more isn’t always better. Overdoing it can lead to a few common problems:
**Hygral Fatigue and Moisture Overload**
This happens when your hair takes in and releases too much water too often. The constant swelling and shrinking weaken the strands, making them feel soft, stretchy, dull, frizzy, and prone to breakage. It’s most common in high-porosity or chemically damaged hair. To prevent it, avoid over-moisturizing and use products that seal in hydration.
**Scalp Issues and Breakouts**
Sometimes, rich oils and conditioners can slide off your hair and onto your skin, especially around your forehead, hairline, or neck. This can clog pores and cause tiny breakouts called ‘acne cosmetica.’ If you notice small bumps near your hairline, try avoiding heavy, pore-clogging products. Your skin usually clears up within a few weeks once you make the switch.
Remember, 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. Do it at the right time, and your hair will forever thank you!
