Piur London - S.P.R. Protein Infusion (1000ml)

What it does

Protein Infusion is Step 1, the first Reconstruction Phase step, of the S.P.R. protocol. Its Marine Bio-Peptide System combines lightweight botanical peptides with marine minerals to help reinforce weakened areas inside the fibre, improving elasticity and resistance without weighing hair down.

How to use it

1. Apply evenly to wet mid-lengths and ends. Do not apply to the scalp.
2. Leave on for 10 minutes; a mild heat source may be used during the pause if the protocol calls for it.
3. Do not rinse.
4. Proceed straight to Step 2, Seal & Protect, applied over the top.
   
   

   When to use it

   Step 1, straight after S.P.R. Shampoo on towel-dried hair, before Seal & Protect (Step 2). Not designed to be used on its own.
