CONDITION, CONDITION, CONDITION!!!
You have to make sure you keep your color treated hair conditioned and moisturized. If you kept your hair moisturized before your colored, you have to do so even more now to make sure the color treated hair doesn't dry out......and that's not necessarily something that will start at the ends. It appears that you have some "chunky" highlighted areas, definitely keep an eye on those areas and take special care.
Since you just got the color, I would go at least every other week so you have your stylist making sure the color isn't causing and damage or anything. And your stylist can see what you can't see and give you the necessary treatments; protein, moisture, etc to keep you on a healthy hair path.
If you admit that you don't take care of your hair then maybe you should consider going to the salon once a week just until you learn how to best take care of your color treated hair from your stylist. Bottom line is you need to take extra care of your color treated hair.
Your hair looks really nice and you might be tempted to wear it straight but TRUST me, I think your color is going to make your curls POP that much more.
I'm not familiar with Linseed Oil so hopefully someone else will respond in that regard in addition to a moisturizing pomade or something that you can use on your straight hair.
I wear my hair curly, in a wash and go, most of the time and color on the regular. It will not break if treated properly (btw, I love your color).
I don't go to the salon. Most of the stuff they do there you can do at home faster, and cheaper.
Since you have color, you very much to take better care of your hair. You need to deep condition weekly, and use a protein conditioner twice a month to repair and prevent damage. This can be as simple as you need it to be, with things from your kitchen cabinets (olive oil, mayonnaise, eggs, honey, and many other ingredients).
There are several threads in the coloring, homemade hair products, all-natural and protein forums which can help you with these deep conditioning requirements. Do a search using the words "deep conditioning", or "treatments". You should find plenty of help this way.
