This root spray has a lightweight, non-greasy formula to add root lift to hair and improve fullness. Perfect for fine, limp hair, this product contains volumising actives and Wheat Proteins to give hair a volume boost.


Key Features and Benefits:


  • Sulphate, Sodium (Chloride) and Paraben free formulation is gentle on your scalp.
  • Gentle formulations are colour-kind, and can be used after Keratin smoothing treatments such as a Brazilian Blowdry or Kerastraight.
  • Contains Wheat Protein which adds ‘substance’ to each individual hair strand both internally and externally for exceptional volume.
  • Contains an Amino Acid Complex which moisturises, strengthens and repairs hair surface damage.


If you are outside of the UK you can find your nearest stockist/distributor here.

Spray evenly onto roots of damp hair, then dry and style as desired.


Use with Thicker & Fuller Shampoo, Conditioner and Plumping Jelly.


Top Tip: Dry hair upside down to boost volume at the root. By doing this you will be drying hair away from the head rather than flattening it, so hair will look thicker and fuller.

    I am unable to obtain your products from Boots now, I have been using your hair products, so I am very disappointed to be unable to buy. The items I use are Styling blow dry mist & Volume thickening spray. Help would be much appreciated.

      Hi Maureen,
      Our products are no longer being sold in Boots stores, and are currently only available in our salons or through our website. The Salon Approved collection which was in Boots has been discontinued, and replaced with our new Salon Care Collection. The closest replacement to the Thickening Spray would be the Thicker & Fuller Root Boost Spray.
      Kind Regards,

    I used your Volume shampoo and Volume Thickening Spray which I found excellent. Where can I buy some or something similar please?

      Hi Helen,
      The Thicker & Fuller range would be the closest replacement to the old Volume range you would have used previously. Root Boost Spray is the direct replacement for Thickening Spray.
      Thank you,
      Trevor Sorbie Team

To reduce frizz try squeezing wet with a towel rather than rubbing it, and use a wide-tooth comb or your fingers to detangle damp hair - never brush your curls, especially when dry.
