I haven't used shampoo in like 3 years why would you spend money on that

Riboflavin improved the quality of my skin, and I think vitamin C is critically important—not just getting the recommended daily amounts, but also eating foods throughout the day that supply it as only so much can be put to use at a time. Vitamin C increases collagen synthesis and helps maintain vitamin E levels. Vitamin E protects against the skin quality lowering effects of polyunsaturated fats. Omega-6 fats increase sebum production (therefore oily skin) and cause acne and eventual hair loss. Copper is important for the coloring of hair, so it's unsurprising that sunlight tends to improve the appearance of hair when it is intimately tied to copper metabolism. Sunlight produces a wrinkled, aged appearance to skin that has lots of polyunsaturated fats within, and topically applied saturated fats such as coconut oil seem to radically reduce sunburn symptoms.

I stopped using regular shampoo some years ago and only use the plainest coconut oil bar of soap for my hair and body. My hair looks fine—perhaps even better than usual because of the sunny weather. Commercial shampoos tend to have questionable ingredients. I don't think it's the job of what you wash your hair or skin with to make them look better—only that it doesn't damage the hair or skin. What you eat and the environment you live in is usually the best way to improve their quality.

Wash your skin with some hippie all-natural bar soap. Look up how to wash your hair with water only, it's probably worth it in the long run. Other than that, ACV and honey are both good. Don't use baking soda, it will destroy your hair if you use if for too long

I've got really bad dandruff. Shaved my head because of other reasons and figured it might get less with that, but it didn't.

I thought dandruff happened because of dry skin, but my skin doesn't feel dry at all except after a shower. Hell, now that I'm a baldy I've noticed the skin on my head getting greasy more easily, but still have dandruff out the whazoo.

What can I do to stop being a flakey cunt, /fit/?

What did the trick for me is never using hot water for the hairs; cold is the best, but lukewarm is also okay. Seawater always cures it during vacations, too.

for skin, you need:

>cleanser for washing your face every morning and night

>exfoliant twice a week after using the cleanser, no more

>moisturizer after the cleanser or cleanser+exfoliant

>sunscreen for if you're going out in the sun

so I would suggest that you buy:

>cleanser

>regular moisturizer

>moisturizer with SPF (use instead of regular moisturizer if you're going out in the sun)

>exfoliant

if you have problems with acne, you can use benzoyl peroxide too, but make sure you don't get it in your eyes or in your eyebrows or on your clothes 'cause it bleaches hair and clothes. research it well before you use it

the exact products will depend on your individual skin, different people react differently to different products. but make sure you search all the ingredients on this website (https://www.ewg.org/skindeep/) to see if they're nasty; you should really put some thought into applying anything rated 4+ on your skin all the time. you also might want to test things on your arm and wait 24 hours to see if you have a reaction first 'cause you definitely don't want your whole face to be all red and itchy or something like that

Anybody have experience or opinions on using olive oil on your face after clean shaving? When I clean shave with a razor my skin is left feeling taught and dry, especially if I overdo it. The only product I use is the lather, a stick of shaving soap applied to the face, worked into a lather on my face with the brush and some water. After the shave I just splash with cold water a few times over a few minutes with minimal drying (drying by pressing the towel against the skin, never rubbing). I've read testimonies/anecdotes/info online of various natural and synthetic products - using oils vs moisturisers vs aftershaves etc. Anyone have any insight to offer?

>Anybody have experience or opinions on using olive oil on your face after clean shaving?

Besides issues with it being adulterated and not genuine olive oil, I don't think putting that much linoleic acid or unsaturated fat in general on a small, concentrated area repeatedly will do good things for the long term health of the skin. While olive oil is one of the safer fat sources people term "vegetable oils", it's usually eaten and filtered by the liver first and afterwards it is given to a relatively equal and balanced distribution over the entire body instead of accumulating in one area of skin or muscle.

The linoleic acid will almost certainly eventually upregulate sebum production and lead to increased acne, and the total unsaturated fat content will likely cause cell membranes in the area to become more permeable and more prone to water retention and later on as aging continues will be more prone to sagging. Puffiness, sagging, and pimples are major concerns, but throw in interaction with sunlight, and you may become more prone to wrinkles as well.

Occasional use of coconut oil, MCT oil, or vitamin E would be safer than olive oil. I think the immediate, direct cause of your face being dry is the use of soap on the face. Personally, I don't think the face has skin which is meant to be washed with soap except under special circumstances. Normally, water is all that is appropriate. Various nutritional remedies may further improve the quality of skin in the long term.

>>140729

Make sure you warm your face well beforehand to prepare it, and you can try slathering on some Jojoba oil before the lather to give some extra protection. Make sure you use moisturizer after you shave.

lol what am I looking at here? Some of it looks like things I've been repeating; some of it looks like stuff you found elsewhere. Do I smell something funny in the wind? Regardless, I feel responsible if you're taking it super serious, so I'll add a couple pointers.

While retinol is the more active form you would want to seek if you are desperate for the vitamin A action you've been missing, beta-carotene is safer in the long term, and its conversion to retinol is somewhat determined on an as-needed basis. Special conditions and sluggish metabolic environments (or perhaps exceedingly fast ones) may call for more retinol though. Someone wanting to see effects fast may go for retinol, but I would advise supplementation always coincide with additional vitamin E. Vitamin A is probably the most dangerous vitamin to supplement, but the payoff is nice if you were in need of it. Both deficiency and excess of vitamin A is associated with enhanced lipid peroxidation, so the message being shouted from the heavens above is once again: lower polyunsaturated fat intake no matter what you choose. Vitamin E attenuates the danger, and its supplementation alone helps restore vitamin A levels by preventing its premature destruction. Excess vitamin A reduces thyroid function and elevates adrenal activity (not good). I strongly suspect that has polyunsaturated fat levels in the body decrease, vitamin A levels will tend to normalize.

>the weight of the thyroid is diminished and that of the adrenal increased

Sometimes the answer is more zinc—not vitamin A:

Smith, John Edgar, Ellen D. Brown, and J. Cecil Smith. The effect of zinc deficiency on the metabolism of retinol-binding protein in the rat. Translational Research 84.5 (1974): 692-697.

https://www.translationalres.com/article/0022-2143(74)90145-0/fulltext

>Zinc-deficient rats have very low plasma vitamin A levels in spite of adequate liver vitamin A stores. A study was conducted to explore the effects of zinc deficiency on the metabolism of retinol-binding protein (RBP), the plasma transport protein for vitamin A. […] The data suggest that zinc deficiency interferes with the synthesis of RBP by the liver and probably with the synthesis of some other plasma proteins as well. The low plasma vitamin A levels seen in zinc deficiency can be attributed to an impaired ability of the deficient rat to mobilize vitamin A from its liver in the form of the retinol-RBP complex.

>that has polyunsaturated fat levels in the body decrease

*that as polyunsaturated fat levels in the body decrease

Regarding vitamin K, yeah, if you're going to supplement, K2 (MK-4, menatetrenone, or menaquinone-4) is the active form that many people report success with and is exceedingly safe albeit there is some competition with vitamin E that may result in one depleting the other.

Farley, Sherry M., et al. Vitamin E decreases extra‐hepatic menaquinone‐4 concentrations in rats fed menadione or phylloquinone. Molecular nutrition & food research 56.6 (2012): 912-922.

https://doi.org/10.1002/mnfr.201100751

It is in all likelihood possible to get away with eating green plants to get vitamin K2 (MK-4). This may be important to point out if I ever indicated supplementation was the only way or if supplements are cost prohibitive or are not easy to obtain in your region. Grass-fed animal products—especially their organ meats and milk—are another route but I caution against relying on this as your sole source because reliable standards and practices of livestock caretakers is warranted as is trust in them. You trust someone today? What's the matter with you?

Additionally, it is important to be replete with riboflavin for vitamin K to have full efficacy:

Besides tocopherol and zinc, taurine is another factor to consider in preventing toxicity from vitamin A excess.

Maybe I should tone down on the hot showers then.

>Seawater always cures it during vacations

Neat. Guess it's to do with the salt?

Water you faggot.

It's really best to make your own soap/shampoo/shaving cream. Your local farmer's market probably has some homemade ones or Etsy. Ingredient lables on hygienics and cosmetics aren't like food. They don't have to list everything so even if it says it only has natural stuff in it, it probably won't be. Avoid artificial dyes. But seriously google a soap bar recipe for your skin and hair type. Buy all the supplies needed for under 15 dollars probably. Have all the soap and you need for an entire year after about 8 hours. Hot process soaps are pretty instant and but cold process soaps have their benefits if you don't have an old crockpot you can use.

To give some background, I tried a load of products to get better skin, including salicylic acid. After all that I just tried the Caveman skin care routine, which was not using any skin care products at all. It was the main thing that helped my condition, but I also might have been overwashing my face at the time.

The results certainly aren't short term I can at least say.

Sunshine.

There's a reason tanned people are never covered in acne, UV radiation kills all the bacteria. Sunbathe or go work outside shirtless for 20m to 1hr a day and your acne will rapidly go away.

If your case is particularly bad, swap out all your usual drinks for Spring Water and Cold Pressed Fruit Juice.
