I straighten my hair most days but wanting to keep the heat off it for drying and let it dry naturally. What can I do to keep it as straight as possible so don’t need too much straightening? If I just leave it, it goes very crinkly and takes a lot of straightening first time! Any tips welcome. Quick tips preferable, takes ages with dryer on cold setting. I have long hair. Any way of putting it up to keep it straighter?
