Yes, the changes in your normal fingerprint occurs. the devices usually reads the image in its capturing structure, if it is colored using henna, the image read by machine is a faded-one
I made a quick search and found this answer in Quora website and I believe it could answer your question:
You get fingerprints because of ridges in your fingers. Henna is just
a paint/dye and your fingerprints don’t get affected by it . But henna
is not universally known and immigration officers from other countries
may suspect it. There have been incidents where immigration officers
did not consider your fingerprints with henna. It is safe if you don’t
apply henna if you are flying to other country. Or best of both
worlds, you apply henna on rest of your hand keeping your fingers
clean.
