    How to use

    To increase the speed of the treatment, apply Retention & Speed Booster with a micro brush on the strip of the extensions in the box or on the lash palette to prevent the lash fan from closing during the "fanning".

     

    IMPORTANT! Do not use on Easy Fanning lashes! Easy Fanning Lashes are made by connecting multiple layers of lashes with a very fine non-cyanoacrylate adhesive. Booster can melt this adhesive, making Easy Fanning lashes difficult to apply.

    Not like it used to be

    I used to love this product I used it all the time but I feel like the product isn’t the same. I feel like something in the product has a different ingredients and it doesn’t work the same. I wish it did because I couldn’t find anything like this. Now I am in the process of trying to something else to substitute this product.

    Hi Athena,

    Thanks for your review. We are so sorry to hear you're not happy with the Booster! This doesn't sound right at all. We have now reached out to you via email so we can look into this further.

    Thank you so much.

    Life Saver !!!!!!

    This product has potentially saved my business. I am a relatively new lash tech still growing clientele. more recently I struggled with retention as I struggled to find a glue to match my environment. adding this product to my prep has made all the difference. The fans literally grab on to the natural lashes. I no longer have to worry about fallout for my clients and my time has also improved. while I did order many other products from London lash I think this one was the key I just had to leave a review.
