Why is my scalp micropigmentation not working? (Photo)

Ive done smp at vinci clinic in beirut n i done my 3rd session 2 weeks ago. Now scabs are starting to peel and take out the ink. The first 2 sessions made no difference to my scalp at all. Im so upset n dissppointed that i spent $1800 on nothing but pain and waste of time ! Note that i was told to moisturize after day 2 for 4 days but after the 3rd sessions i felt that i need to hydrate more so im still applying moisturizer till now . Please tell me what should i do
