  1. Providing proper nourishment to your scalp
  2. Treating hair damage
  3. Frizz Control
  4. Making your hair feel soft & smooth

All while leaving your hair healthy & shiny!

Two amazing products that we can’t decide between are the Hair Serum & Leave-in.

Both provide amazing results on their own, but when united, they will give you the ultimate recipe for a silky-smooth hair!

It all comes down to….

How and when do we use different hair care products to reach the “Good Hair Day” goal?

Hair Serum Vs. Leave-in

It’s obvious from the texture that hair Serum is more condensed than Leave-in. This is due to the difference of the main substance they are both made of. Hair Serum is oil based, while the Leave-in is water-based. In addition to other ingredients, these two complementary products are an essential powerhouse for a soft & vibrant hair.

When should you use each?

Both products protect your hair against a variety of hair damage problems that may occur.

They give your hair the elasticity it needs by providing hydration to your dry hair. They also control frizz, by providing your hair with extra moisturizing elements. In addition, both products help in repairing hair damage caused by heat and chemicals via strengthening your hair strands.


  • Leave-In comes first, since it usually works as a foundation for your hair.
  • It also protects your hair from the harmful UVA & UVB lights.

Hair Serum

  • Hair Serum comes next after styling and heating, providing your hair with that extra shine you seek.
  • It controls the frizz as it adds an extra layer which acts as a shield, keeping your hair safe from undesirable elements.

How to use each?

Always remember that Leave-ins must be applied on thoroughly cleansed hair.

  • Leave-ins can replace conditioners, but if your hair needs more nourishment, then condition it while ensuring that you wash it all out. 
  • Use your microfiber towel to absorb the excess water after your bath.
  • Gently apply the right amount of product on your hair.
  • Detangle your twigs with a wide-tooth comb.
  • Allow your hair to naturally dry or you can use a dryer.
