DIY Beauty: sea salt water to thicken fine hair

Those with fine, flyaway hair might want to give this simple DIY hair recipe a go! I read somewhere awhile back that sea water is good to thicken hair but since I don’t live near a beach, I thought this can be replicated by using sea salt from my kitchen! I’m all for a more natural way to thicken my hair without resorting to commercial products so if you’re like me, read on.

Sea salt for volume & control
It seems that sea salt water can give our hair some volume and control. In fact, I understand it’s great for to make wavy hair wavier than normal. But given I have straight hair, and so I can only try this for volume and control. I’ve taken the sea salt water for a couple of rinse so far and it indeed does what it promises! My hair feels thicker and easier to tame and style. I am kind of loving this except that I also know that using too much salt on our hair can be drying.

Not table salt
The recipe is so easy. All you need is sea salt. No table salt please. I mix about one tablespoon of salt with 300ml of water. Well, I’ve found out the more salt there is in the water, the better the effect. And I use this as the last rinse after I have given my hair a proper wash. Another way to try is to contain the sea salt and water into a spray bottle for styling purpose. I haven’t tried this because the rinse works better for me as it’s totally fuss free. But I suppose a spray bottle will suit those who want to make their wavy hair wavier as a spray bottle makes styling more convenient.

Cost saving
I understand that some hair products that promises volume or wave actually contain sea salt but well, I suppose they’ll cost at least $15 or more. So instead of forking out that kind of money, why not just give this a try? It certainly worked for me!

    REALLY? I’d def think that it would dry your hair out. My hair is dry and thin, do you think I should still try it?
    How many times a week do you rec that we do it? I wash my hair every other day.
    I’ll def have to try this at least once! ? My fine hair makes me so sad!

  2. aibicon says:

    Hi Sesame,
    do we wash only the end of our hair without touching the scalp?will I have more hair fall if I accidentally touch my scalp?

  3. Jyoan says:

    Interesting, I’ve never heard of it. Unfortunately, my hair is already so thick and wavy, and I don’t like it to curl even more. Lol.

    Means you tried dissolving the salt till saturation point?

  4. Chenyze says:

    hmm, so you actually leave the salt water in the hair, rather than rinsing it out again?

  5. Nika says:

    This is something totally new for me.
    But when I think about it, I remember that every time I spent a day at the beach, my hair looked great and wavy. Well, it is too short now.

  6. sesame says:

    Yes, hair texture always feel thicker after a swim at the sea for me.

  7. sesame says:

    Yes, last rinse and leave the sea salt water in the hair.

  8. sesame says:

    Yes, dissolve till saturation and the water will feel slightly ‘slimy’.

  9. sesame says:

    I was a bit concerned about that but I thought logically, it shouldn’t cause more hair drop. I tried a bit times and it was fine. If you’re concern, then the spray method would work better.

  10. sesame says:

    So far, it seems okay for me. I don’t see my hair drying out but I guess it will with long term usage. I don’t do this every day though. Like two or three times a week.

  11. Swati says:

    oh yes, salt does thicken hair but it dries too ? but its great for de-frizzing the hair…saw it in one of the videos!!!

  12. Amanda says:

    That’s interesting. I thought salt (regardless of which kind) can only dry our hair. I never thought of using it on my hair! I have a small pack of dead sea salt and don’t know how I could use it because the granules are too large. Now, I can put them to good use ?

  13. Liesl says:

    I love John master’s sea mist with lavender spray on.
    So perhaps for some extra shine and a nice scent, we can add in some drops of essential oils as well?

  14. sesame says:

    Yeah, for sure. ?

  15. sesame says:

    I think the drying part is true if frequently used so this has to be used in moderation.

  16. claire says:

    I shall get a bottle of lavender hydrosol and dissolve some sea salt in it! a cheaper alternative for john masters sea mist spray. I shall be needing this once I get my hair rebonded! :/ can’t stand flat hair but my hair is dry and wavy naturally with lots of baby frizzy hair and it gets so voluminous that my sister exclaims it’s retro. thanks for the tip off!

  17. Audris says:

    I do think it’s true. When I look back at my college photos or even my dive holiday photos, my hair always appears fuller, even when slightly damp. Has to be all that sea salt!!!

  18. Vivian says:

    I dont think sea salt is a good idea. It makes your hair rough (probably the reason why you think it poofs up). Think of how rough and damaged our hair feels like when you dip your hair in the sea.

  19. Andrea says:

    Does it leave behind any salt crystal residue, especially once the hair has dried? I’m going by the logic that they used to tell us in school – that if you leave salt water out in a dish, once the water evaporates, it leaves the salt crystals behind again. Does it happen with your hair?

  20. sesame says:

    You’ll need a bit of the sea salt…the mixture should have a ‘slimy’ feel to get a thickening effect.

  21. sesame says:

    Yeah, I remember that too. But I also remember I needed more washes to get rid of the residues from the sea water.

  22. sesame says:

    Like I mentioned, if you wish to try this, use in moderation cos it can be drying.

  23. sesame says:

    Hmm…not that I could feel cos the sea salt I used were very fine but they’re possibly there somewhere.

  24. Viv. A says:

    This is also a nice tip for those with wavy/curly hair and want that “beach look”, but you people are right abut the drying part, so try to use it in moderation. I also have used the sea salt with leave in conditioner instead of water, and the results are fine too.

  25. Anu says:

    I’d imagine sea salt would make my hair feel sticky rather than dry. Doesn’t the salt water feel sticky to touch? But an interesting experiment. I’d start by adding it to my conditioner and see what it does. If not thicker hair, wavier hair sounds pretty good too. My sis gets quite mineral-rich water where she lives and her hair has certainly turned wavy at the ends over a few years.

  26. sesame says:

    Hmm…it’s not sticky but the feel is somewhat like you’ve used some hairspray. You try it and see if it works for you. ?

  27. sesame says:

    Oh that’s a good idea! Sea salt with leave in conditioner!

  28. Miss Vinny says:

    Hhmmm…. how would you mix in sea salt with leave-in conditioner? Use a spoon to blend it all in?

  29. sesame says:

    I’ve not tried this but I think what you just suggested make sense…or a stirrer. The fine sea salt should blend in well. I don’t use leave-in conditioner.

  30. Katie says:

    I really want to try this! Just have to buy some sea salt. My hair is ridiculously thin and doesn’t style well. At this point it couldn’t hurt lol.


  31. Sesame says:

    It works!

  32. Something says:

    Will this work for curly hair too? I have been looking all over for good hair treatments to help with my natural, but extremely frizzy and dry curly hair. I use Hot Oil treatments but I feel like I should do more to help with it. ?

  33. Sesame Chew says:

    It should but you need to give it a try to know for sure.

  34. http://www./ says:

    Great insight. Relieved I’m on the same side as you.

  35. http://www./ says:

    That’s not just logic. That’s really sensible.

  36. Deborah says:

    I read that instead of washing hair so much, we need to just do medium warm water rinses with gentle messaging so that we don’t lose our natural oils. Just a thought to help.
