Top 10 Hair Serums

Top 10 Hair Serums

Hair Serums are the secret to that incredible glossy result you get at the hair salon. They help to smooth frizz, add shine, boost strength and hydration, all in just a few drops. No surprise then that they have become an everyday essential in our haircare regime! We’re letting you in on the best serums on the market, for every hair type, so you can discover the incredible results for yourself.

Why Use a Serum?

Hair serums are finishing treatments which give you gorgeous styling results whilst also boosting the condition of your hair. They usually contain silicones or oils to smooth the hair cuticle and protect from the impact of sun, humidity and pollution whilst adding incredible shine.

You can find them in almost every kind of formula, from oils to creams and pumps to sprays, so there is a serum for every kind of hair, even fine hair. For the best results:

  • Apply to towel dried hair, not wet hair as otherwise the oils can mix badly with the water to leave hair feeling greasy.
  • Focus on the lengths and ends of the hair rather than the roots and scalp
  • Use serums after heat styling to remove static and smooth out the hair cuticles.
  • Use serums a day or two after washing if you have Curly hair, instead of straight away. It works better to revitalise curls and smooth frizz.

Beauty is my absolute passion and even having worked in the Beauty Industry for six years, I still love to spend my spare time trying out new discoveries. From red lipsticks to electrical facial devices, I'm always willing to trial the next best beauty product. When I'm not at work I try to explore the USA, so I'm always on the hunt for mini beauty samples to pop in my travel bag for my next flight to NYC.
