Welcome. I commented on your profile, already. But I'll reiterate it here too. Trash everything you've got. DHHQ doesn't accept returns easily, and when they do, they charge outrageous restocking fees. And if you mention that you want to grow healthy locks,they won't even get back to you about any returns.
All of the good reviews on their page are from people who "put in" their locks that day. Once they realize how damaged their hair is, DHHQ censures those reviews.
I know you spent a lot on their products, and may not want to lose that money, but chalk it up to a learning experience.
You've got to remove that wax, though. Wax only prevents locking and creates a perfect environment for mold and mildew. Dreadlocks rot from the inside out. So you may not know how damaged they are until the wax comes out. It's a very aggressive washing routine, but it has to be done it you want to keep your locks for another 5 years. Check the dreaducation page, and the wax removal page. If you need any help, or clarification, let me know. I can help you get it out. Because you've been using wax for so long it'll take a while to get it all out (Most of it is hardened in the core of your locks, making them feel more mature than they are). But it's really necessary for your hairs health
