Rub your hands together to spread the serum evenly. This will help avoid clumps in your hair.
Apply the serum to the ends of your hair first. This is where most damage happens.
Work your way up toward the roots, but avoid putting too much serum on the scalp.
Use a comb or your fingers to distribute the serum evenly throughout your hair.
Now you’re ready to style your hair as you like. You can blow-dry or flat-iron it for a sleek look.
Tips for Maintaining Sleek Hair with Serums

Use only a small amount of serum. A little goes a long way; too much can make your hair greasy.
- Apply the serum from mid-length to the ends of your hair.

- For extra shine, apply a small amount to your finished style.
How to Choose the Right Serum for Your Hair Type

If you have thick or curly hair, look for a serum that provides deep moisture and control. These will help to tame frizz and make your hair easier to straighten. For thin hair, choose a lightweight serum that won’t weigh your hair down.
Additionally, check the ingredients. Look for serums with natural oils like argan or jojoba, as they are great for adding shine and smoothness.

The Science Behind Hair Straightening Techniques

Different techniques are used for straightening hair. For example, flat irons use high heat to smooth the hair shaft. Other methods may use chemical treatments to relax the hair. Each method can give you sleek hair, but they can also affect the health of your hair over time.
- Heat-based techniques can cause damage if used too often.
- Chemical treatments can lead to dryness and breakage.
- Using a serum can help protect your hair from damage.
