Can You Leave Conditioner in Your Hair Overnight?

Deep conditioning hair masks are great for conditioning, soothing and softening our hair. If you love what your deep conditioner does for your hair, you may consider using it overnight. But be mindful that many hair masks are not formulated to use as overnight deep conditioners.

Some deep conditioners have ingredients that can weigh down your tresses, making them dull, limp or gummy if left on too long. However, lightweight masks can take overnight deep conditioning to the next level when used with a hot terry-cloth turban wrap.
 

What Are the Benefits of Deep Conditioning Overnight?

Many of us find our hair becoming weaker, thinner and more easily damaged as we go through perimenopause and then menopause. This is because our estrogen levels taper off, and dihydrotestosterone (DHT) takes over, shrinking our follicles and impacting the thickness, vitality and overall look. 

Using your deep conditioning mask overnight can help revive dry, weak tresses and enhance your hair’s manageability and appearance. Nighttime conditioning can:

  • Nourish your scalp
  • Tame frizz
  • Add a glossy shine
  • Reduce breakage
  • Diminish knots and tangles
  • Hydrate your hair shafts
  • Improve hair cuticle health

Is It Safe to Use a Deep-Conditioning Hair Mask Overnight?

Think of your overnight deep conditioning mask as your regular hair mask but upgraded to deliver nourishment to your strands as you snooze. Some deep conditioners are created to be left in place longer, allowing ingredients to penetrate your strand’s cuticle layer and pass into its inner layers.

Other masks may contain ingredients only recommended for short periods.

Deep Conditioning Masks with Restorative Ingredients


Better Not Younger’s Hair Redemption Restorative Butter Masque and Silver Lining Purple Butter Masque were formulated with five plant-based butters to be safely worn for hours. They deliver nutrients to combat dryness, split ends and more with ingredients including:

    • Avocado butter: Avocado butter coats your strands and efficiently delivers vitamins and amino acids into your hair shaft, improving shine and flexibility.
    • Murumuru seed butter: Murumuru seed butter is rich in omega fatty acids, myristic acid and lauric acid to increase the combability and of your hair. It controls frizz and locks in moisture without weighing it down. 
    • Cupuaçu butter: Cupuaçu butter smooths, moisturizes and strengthens your hair’s protective cuticle layer. It contains lauric acid and stearic acid to coat and protect your hair while reducing frizz.
    • Macadamia ternifolia seed butter: This lush butter reduces oxidative stress on your scalp with naturally occurring squalane. It strengthens your hair while nourishing and hydrating your follicles. It’s also loaded with calcium, magnesium, iron, copper and fatty acids.
  • Mango seed butter: Mango butter contains a mix of essential fatty acids that help balance your scalp’s sebum production. They also soften your strands while safeguarding them from environmental damage.

  • Deep Conditioning Ingredients that You May Not Want to Use Overnight

    You should only use masks containing the following ingredients for limited periods:

    • Apple cider vinegar: Avoid using overnight conditioning products with higher concentrations of apple cider vinegar. If left on for too long, this acetic acid could strip protein from your hair and dry it out.
    • Egg: Egg is a popular ingredient in DIY hair masks. However, leaving an egg on your hair overnight could collect bacteria and produce a bad smell. 
    • Protein: If you’re only using protein treatments for 15-20 minutes or so, they work great. However, using them on your hair for multiple hours at a time could weigh down your hair and lead to breakage.

    How to Use a Deep Conditioning Hair Mask Overnight

    We generally recommend using our masks or conditioners on the ends and mid-lengths of your strands. When your scalp is dry and itchy, it can benefit from weekly deep conditioning, which can ease inflammation without clogging your pores.

    To experience even more hydration, use our hair mask overnight for an intense monthly deep conditioning treatment by following this procedure: 

    1. Before going to bed at night, wash your hair with your regular shampoo. 
    2. Gently wrap or dab your hair with a soft towel to remove excess moisture.
    3. For normal or oily hair, rub a dime-sized portion of the hair mask between your palms. Use more if your hair is dry or damaged.
    4. Massage the hair mask into your strands from root to tip, focusing primarily on the ends.
    5. Run a wide-toothed comb through your hair to evenly distribute the moisturizers.
    6. If your hair is long, wrap it up around your head and secure it in place.
    7. Cover your wet hair by wrapping it in a hot, damp towel. The steam from the towel opens the pores on your scalp while the heat relaxes your hair’s cuticles. This allows the mask to permeate your strands more deeply, making a more significant impact on your hair and scalp condition.
    8. Place a dry towel over your pillow to rest your head on while you sleep. This will protect your pillow if any of our buttery mask escapes from your wrap.
    9. In the morning, rinse your hair and scalp thoroughly to remove all traces of the mask. 
    10. Style your hair as usual and enjoy silkier hair and a more hydrated scalp every time you deep condition overnight.

    Heat steaming with a hair turban helps our Restorative Butter Masque ingredients penetrate even deeper into your scalp and hair.
