Top of my head looks awful!
Help! Save My Dreads
Sorry to hear you got taken in by a salon.$$$ If the owner who did your dreads really knows his stuff, then why do they feel like you can pull them apart??? Crochet hooks break the hairs into little pieces everytime that hook goes through, that breaks the long strands inside and outside the dread/section. That is why they feel like you can pull them apart. Crochet hooks and wax are the two worst things for dreads.
Do yourself a favor and do not use dry shampoo for your dreads or cover them with a cap to keep them dry when you shower, they need to get wet and clean. I think by now your scalp needs a huge baking soda cleanse. When you do it you will find a lot of dead skin washing off your scalp.
It will take about 6 months or so to feel a difference in the crocheted dreads, they will take time to repair if you keep them healthy and clean.
