What is on your mind?

I would like to out a new segment where you (the reader!) decide what you want to see on the blog.

You can
1. Suggest a topic to research
2. Ask for an explanation or clarification of a previous topic

If you like someone else's suggestion, place it in the comment box. The suggestion with the most support will be the featured topic. This is a request for one topic only, make sure it is what you want to read!

Commenting is open from now until Friday the 6th of August.......................What is on your mind?

  1. I'd love to see stuff about conditions that could affect the health of the scalp. I know you have a lot of information on your blog already, but it'd be lovely to have that all in one place.

  2. asimplething - Do you mean remedies for scalp issues or do you mean products that may cause scalp problems?

  3. I would like more information on propylene glycol. Why or why isn't it bad/unsafe? What are your thoughts about it and would you/do you use products with it in it?

  4. I'd like to suggest a topic on sunscreen. There seems to be different standards across different countries, whether certain ingredients are approved or not. There's also talk in beauty forums that certain sunscreen ingredients e.g. avobenzone are not stable with makeup, or how makeup would de-stabilize sunscreening agents.

  5. Is aloe vera juice a humectant? Keep hearing that, but don't know for sure.

  6. I would love for you to address your finding that the cuticle step height doesn't change significantly, i.e. "lift" between a pH of 4 and 9. I read that article you referenced, and it seems as though the cuticle step height changes significantly-- from 500 nm to 1000 nm, and then raising to 1500 nm at a pH of 11+. I do not understand how you came to that conclusion when reading that article.

  7. Can Henna or Amla affect the natural curl pattern -- if so, how.

  8. I would like to know if it is bad to oil the scalp. I read somewhere that it inhibits the production of sebum. Is this true?

  9. Delphi - Just answering your question because it is quickly answered. Reading a graph starts with focussing on the error bars because these tell you about how the data is spread. If you pay attention to the error bars, you will notice that they overlap alot. The lowest point of the pH 8 error bar for example overlaps the pH 4 error bar. This means that at pH 4 and pH 8 there are similar values (i.e they are in the same data range).

    The question to ask yourself when attempting to plot a line through data is first and foremost, do the error bars overlap?

    The error bars at pH 10 and 12 are the only ones that do not come into the frame.

    In short scientifically the error bars are most important because they tell you the probability of a data point occuring at a specific value.

    I try to keep scientific jargon out of my posts but explaining graph reading means I cannot avoid this. I hope this makes sense, if it doesn't feel free to ask again.

  10. I would like to know if it is bad to oil the scalp. I read somewhere that it inhibits the production of sebum. Is this true? As my2gurlz suggested

  12. Jc, a lot of people are raving about ceramides, could you explain what they are and their functions?

    ReplyDelete
  13. I second Milan's suggestion.

  14. Thanks for the suggestions. Lady Swag you indeed remind me that I had promised to do a ceramide post ages ago!

  15. Keep the suggestions coming, I will close it on Friday which gives me the weekend to do the research :)

  16. I second Lady Swag's suggestion on ceramides.

  17. Can you talk about scab hair?

    ReplyDelete
  18. I too have to agree with LadySwag and say ceramides.

  20. I would like to know about ceramides too please. I mainly wash with conditioner, and so one of the things I would like to know is if ceramides can build up on the hair like some silicones do.

  21. Are you still going to do those Monday segments on ingredients?

    ReplyDelete
  22. Hey I have another one. What about irish moss? I hear a lot of ladies swearing by it to condition with. What is it and why is it good?

    ReplyDelete
  23. Anon on Monday segments on ingredients - I am actually working on this (or rather making my husband work for me on this lol), I want it to be like an A-Z section and I am not sure how to fit it onto the blog. I think it will take a couple of months to collate and then I will figure out how to put it up properly.

  24. On the site NaturallyCurly there is a passage in reference to using shampoo bars that states:

    "Another potential hazard of the shampoo bars and soaps is that they typically have a pH in the 8 to 9 range, which is substantially more basic than the natural level for hair. This can result in a temporary breakage of disulfide bonds in the keratin protein of the hair, which can disrupt curl formation and cuticle structure."

    I recall you stating that hair is not disrupted at pH levels lower than 9-10, so I am wondering if this claim about the dangers of poo bars is substantiated? (I just started using poo bars and I'm thinking this is what I've been needing all this time, ha)

  25. I would also like to know about scab hair...is there such a thing? Thanks for all your research!

    ReplyDelete
  26. OK, finally sitting down to ask my questions...I've been thinking about this all week and glad to see so many other ladies have posed some really good ones too.

    1. How similar or dissimilar are the suggestions about natural hair care to permed hair?

    2. What things should we take into consideration when determining facial cleaning methods/products? Especially considering that the pH is similar for hair and skin.

    3. What does coloring do to hair? What is the difference from box color, rinses and powders like henna or alma?

    4. Were you already with your husband when you went natural? Have you ever told your natural hair story?

    Thanks so much JC!

    looking forward to that ingredient archive...send our note of appreciation to Mr. Natural Haven

  27. I think the scab hair topic would be interesting. Too many opinions going around about that. What are the facts!!!

    ReplyDelete
  28. I want to know about hair breakage. Why does my product that only contains honey and sugar do a better job than this product that contains wheat germ protein?

    ReplyDelete
  29. i would like to know how curls get defined. for example, what does it mean scientifically to "define" a curl? having an understanding of how you define a curl would help me to pick out products that define my own hair well! thanks. love your blog!

  30. I would like to know about hard water effects on curly hair! I've just started using products for hard water, but really want to know what's doing the work - the shampoo or the conditioner?

    ReplyDelete
  31. I also would like to know about oil on the scalp and what product is best

    ReplyDelete
  32. How do you safely and successfully elongate your curls? Curl shrinkage is a big problem for natural African-American hair...

    ReplyDelete
  33. This is kinda a hard topic because it will be hard to prove scientifically. I want to know more about cutting or trimming your hair according to the lunar cycle. The Morrocco Method has a chart up on their website https://morroccomethod.com/lunar-hair-chart that shows the best days to cut your hair.
    I want to know if this works (I've heard plenty of positive testimonials) and why it works.
    Thanks in advance

  34. Jc, I would like to know if hair classification (typing) is important & can knowing this assist with product selection and hair maintenance. Thanks So Much

    Thank you for taking the time to help us in need of assistance.

  35. Co-signing on the concept of scab hair. Assuming it's real, I don't think it's anywhere near as prevalent as some think it is. Would love to hear your take on it! Thanks.

    ReplyDelete
  36. Natural products vs. homemade products - i.e., if the product only contains natural ingredients that I can get myself, why or would the product work the same as something homemade?

    Also, the differences between thick and fine hair types - should there be different protein (keratin, wheat, ex) used for each type? Does hair react differently to each protein source?
