Winter may have just begun but the season’s harsh and frigid temperatures have probably already started to wreak havoc on your hair. Wearing knit hats may keep you warm, but they also leave your hair looking flat and staticky. Plus they don’t actually protect your hair from the cold, dry air, which sucks out moisture from your strands leaving them brittle and broken.

Thankfully a deep conditioning treatment is a quick way to give your dry and damaged locks some much needed TLC without breaking the bank. These nourishing formulas work to moisturize, repair, and protect your hair from any future damage. Perhaps best of all, you can actually see salon-quality improvements in a matter of minutes.

Not only will the right deep conditioning treatment transform the look and feel of your locks, but it can also improve your hair’s health. Some feature ingredients that work to boost natural hair growth, while others work to increase strength and flexibility of individual strands.
