Hair Trial Tip?

Hi Girls,

I had my first hair & make-up trial this morning and it was comlimentary. Are we supposed to give a tip or do they incorporate the trial into the wedding day prices? I obviously plan on tipping them the day of my wedding when I use them.

Please let me know if this is the norm! I can always send them a tip in my thank you card when i mail back the extensions they used for my hair.

Thanks girsl! I'll post the pics as soon as they send them to me :)
