  • Naturally present within the hair, it is reach in nitrogen and it is the key component of the formulation (constitutes more than 10% of its composition)
  • Its positive charge ensures effective adhesion to the hairs,

  • Natural humectant that attracts and retains moisture, forming a barrier that protects lashes from dehydration and breakage
  • Its conditioning action makes hairs softer and more flexible, resistant to any damage that may result from some aggressive make up products and treatments.


Rebalancing complex:

  • Prepare the eyelashes with InLei® Saline Solution using InLei®Minions - microbrush.
  • Apply InLei® InPatch or InLei® Black Reusable Pad eyepatches to secure lower lashes and protect the skin under the eyes.
  • Place a selected size of the InLei® Silicone Shields on the clients eyelids and if necessary secure the shield with InLei® Fixing Gel.
  • Align the eyelashes in the desired direction using InLei® Fixing Gel, InLei® Fillering Tool and InLei® Helper or Helper 2.0.
  • Apply InLei® Lash Form1 (first substance) 1.5 / 2 mm from the roots of the lashes using InLei® Vincent cat-tongue brush. Place a thin layer of product without applying it on the tips. Leave on for 6 to 14+ minutes depending on the structure and porosity of the hairs. 
  • Remove the product with with InLei® Vincent brush.
  • APPLY InLei® Lash Fix 2 (second substance) following the same procedure as the previous one and leave on for half the time plus one minute. (For example, if Form 1 was left for 8 minutes, you would leave Fix 2 for 5 minutes).
  • Remove the product with with InLei® Vincent brush.
  • Mix the InLei® Tint with InLei® Developer Cream 1.5% 5 vol. in a ratio of 1:1 inside the InLei® Trio bowl. Mix with a spatula until reaching a creamy consistency. Apply the tint along the entire length of the lashes, from root to tip, using InLei® Vincent or Picasso brush. Leave on for 6 to 12 minutes depending on the type of hair. The dyeing of the lower lashes can be done at this time or at the end of the treatment with the client sitting.
  • Remove the tint with dry cotton tips.
  • Apply InLei® Lash Filler 3 (third substance) using InLei® Picasso and do quick movements to clean any tint residue. Let the product penetrate until complete absorption. For an even more precise and clean work, it is advisable to brush the roots with an InLei® Softies microfibre-tip brush, soaked in InLei® Lash Filler 3.
  • Final cleaning with InLei® Mousse Magica - professional eyelash shampoo. Fill the InLei® Barolo bowl with water and dispense the mousse into the InLei® Solo bowl. Wet the brush and use it to pick up a small amount of product. Meticulously clean any dye residue and dissolve the water-soluble glue until the shield unsticks. Clean the entire eyelid with the brush to remove all residues of glue and comb the lashes with an InLei® F-brush to divide the hairs to one another. NOTE: To obtain the correct consistency of the mousse, it is recommended to shake the bottle and turn it upside down during dispensing.
  • Apply InLei® Lash Molecular 4 - Molecular reconstruction for eyelashes and eyebrows. Apply the product on all lashes using an InLei® F-brush and comb until it is completely absorbed. The molecular reconstruction is a leave-on product.
