This is a very common question within the lash lifting community! Firstly, it should be noted that bonding serum is soluble which means it will begin to dissolve as you apply the solutions.
When you first apply the bonding serum, please make sure you are waiting a couple of seconds for the bonder to become tacky before attempting to adhere the lashes to the shield. Work in small sections and try to get the happy medium between too much and too little bonder. If you bonder becomes white and flakey, it probably means you have applied too much. If your lashes do not adhere, you have probably applied too little.
You can apply more bonder to the tips of the lashes as you do not apply solution to this part of the hair so your bonder will not dissolve in that area. If you find that your lashes begin to come loose throughout the treatment, we recommend using micropore tape after you have applied step 2 to the tips of the lashes to keep them in place.
