Curl pattern disturbed easily Why?

Curl pattern disturbed easily Why? My hair was dyed but whenever I comb or brush, some of my curls go away never to be seen again until I wet it the next day... :/

I don't if this is the same for you - but with my hair, dye can alter my curl pattern. I had to experiment until I found a technique that works for me to prevent the altering of my curls.

Are there any products that you can suggest for me?

I don't particularly like suggesting products because they don't always give everyone the same results.

After dyeing my hair I DC with Lustrasilk cholesterol for a very long time. Like hours and sometimes overnight. Then after rinsing I make sure to sealing my hair with a lot of any creamy moisturizer and some oil.

I have FOTKI albums from two dye jobs that I have done:
