Deep conditioning is known to have many benefits for your hair. But what happens if you leave conditioner in your hair overnight? Let us find out!

The benefits of deep conditioning are no secret to the world. Hot oil massages have existed for centuries and have helped countless people manage their dry locks. The new age conditioners are another boon with their ease of application, fragrant smells, and instant results. Regular conditioning is an important step in your hair care routine. But does going the extra mile and leaving the conditioner on your hair overnight help? Let us find out!

    Why do you need a conditioner?

    Dry and damaged hair not only impacts your appearance, but is also extremely hard to manage. Moreover, dryness of the hair shaft can cause tangling and lead to breakage. But a deep conditioner (aka a rinse-out conditioner) can help you get rid of these issues. Regular conditioning can hydrate your hair, make it more manageable, and repair some of the damage caused by pollution, heat, and dirt.  

    How does a conditioner work?

    Hair conditioner is a cosmetic hair care product that returns moisture to your hair. Hair conditioners contain cationic surfactants that help form a protective layer around the hair strand. Cationic surfactants have a positive charge that binds to the negative charge of your hair strands surrounding them and forming a protective coating that keeps your hair shaft well-nourished and hydrated for several hours after use. 

    How does a conditioner work

    Often conditioners are formulated with oils that make your hair smoother and easier to detangle after a wash. In addition to this, they help prevent and undo some of the damage caused by regular heating products like blow-dryers, curling irons, and straighteners. 

    What happens if you leave conditioner in your hair overnight?

    Now, you might feel that the more you condition your hair, the better it is. This can be true to some extent, but it does not always benefit you in the long run. Regular conditioning can help you maintain a smooth texture, but you should limit applying rinse-out conditioner for a maximum of 15 to 30 minutes only.

    Over conditioning can lead to hygral fatigue. Hygral fatigue is a condition where your hair cuticles swell up due to extra moisture from conditioning too much. Leaving the conditioner overnight can result in hygral fatigue that can wreak havoc on your hair. Some common symptoms of hygral fatigue include the following:

    • Hygral fatigue from over-conditioning can lead to breakage. 
    • Hygral fatigue can damage the hair cuticle.
    • It can cause tangling and unruly hair.

    • It can lead to scalp and hair build-up and attract dirt that ultimately damages your hair and scalp and can increase the risk of developing infections. 
    • Over conditioning makes your hair lifeless and dull. 

    Hygral fatigue is more common in damaged hair, as overly damaged hair is often more porous. The cuticle layer of porous hair is often already broken, which exposes the hair’s cortex, making it vulnerable to damage.   

    What can you do to ensure better hydration for your hair?

    Deep conditioning is important to ensure hydration and nourishment, but only as long as it is done properly. Remember that anything in excess is bad. So try to stick to hair care basics and use every product in the right proportion. The following tips can help:

    • To wash your hair and condition it safely and properly, use a sulphate and paraben-free shampoo and conditioner suited for your hair type and texture.
    • Use a conditioner every time you shampoo, but make sure not to leave it on your hair for more than 15 to 30 minutes. 
    • Understand that a conditioner is not the same as a hair oil. While you can apply natural oils like coconut oil, argan oil, jojoba oil, etc., to the scalp or hair and leave them on overnight for better hydration, a conditioner should not be left overnight, nor should it be applied to your scalp.
    • Understand the difference between leave-in conditioners and normal (deep) conditioners. Leave-in conditioners are meant to be applied to your hair after shampooing and conditioning and before styling. You do not have to wash them off after each application. On the other hand, a regular rinse-out conditioner must be washed off after a few minutes. 
    • Remember that your hair is made up of 12 to 15 % water. It also contains calcium, zinc, iron, copper, etc. Hence, one of the best ways to nourish and hydrate your hair is to ensure that you get these nutrients in your diet. Ensure to drink enough water and maintain a healthy and well-balanced diet of nutritious vegetables and fruits to promote overall hair health. 

    Haircare does not have to be complicated. Using natural products without sulfates, parabens and other harsh chemicals can help you take care of your tresses without any fuss. Always use hair products in moderation and know how and when to use each product to boost its efficacy. If you suffer from extreme dryness, you can also consult a dermatologist for a detailed diagnosis of your problem and a personalized haircare plan.    

    What products help lock in moisture in your hair?

    If you have dry hair, you can make a habit of using a leave-in conditioner on your hair. This is a fat better choice than experimenting with your regular rinse-out conditioner and trying to leave it on for more than you’re supposed to. 

    Here are two products that are easy to use, completely hassle-free, and can be applied even while on the move:

    The 10-in-1 Hair Revitalizer Spray can help you tame frizz, reduce dryness, and improve the appearance of split ends. This leave-in conditioner contains the goodness of sweet almond oil, extra virgin olive oil, jojoba oil, grapeseed oil, Moroccan argan oil, safflower oil, bhringraj extract, rosemary, vitamin e, and tea tree essential oil. 

    The 10-in-1 Apple Cider Vinegar Mist Tonic hydrates your hair and makes it soft and easy to handle. Apple cider vinegar can help balance the pH level of your hair and scalp and it also helps to make your hair smoother and easier to detangle after a wash. This mist can be used on the face, as well as your hair.
