If not kept properly nourished and hydrated, your hair can become brittle and split or snap off completely. Luckily, deep conditioning hair masks are always there to save the day! They're a great way to restore your hair's healthy, natural glow when it becomes dry, dull, or just a bit lackluster.
The main purpose of a deep conditioner is to replenish lost nutrients and moisture to your hair, which can become especially important during the summer months.
How often should you use it?
You should try to use a deep conditioning hair mask on a weekly basis, especially if you do a lot of heat styling. Using hot tools regularly is one of the biggest causes of damaged hair, so it's essential to protect your mane as much as you can.
That said, you shouldn't overuse hair masks because they can start to weigh your hair down. Stick to once or twice a week for the best results.
What to do
After shampooing your hair, apply a quarter-sized amount of the deep conditioner. Add more as needed for particularly long or thick hair, focusing on the lengths and ends. As with your regular conditioner and leave-in products, it's best to avoid putting it on your roots.
Let it sit for however long is recommended on the container, usually 3-5 minutes is enough. Rinse your hair out thoroughly, then wrap it up in a towel to soak up the excess moisture when you step out of the shower.
