The Caramel Treatment - A Natural Hair Softener
The caramel treatment is a product in the E'tae product line. Boasting an all natural line up of ingredients from honey, bananas to olive oil, this product delivers in its ability to seriously soften and hydrate the driest and roughest hair textures. It helps people who relax their hair to 'stretch' their relaxer for longer periods and helps people with natural hair by softening its texture for easier detangling and manageability.
The results of the caramel treatment are not permanent; they last for up to 4 weeks so should be reapplied monthly for continued benefits. Many report 'loosening' of hair texture as well as less shrinkage after the treatment but this is likely due to the added weight of the product as well as the increased moisture levels in the hair. For this reason, the caramel treatment is excellent for helping to straightening the natural hair as it takes less heat to get smoother results as well as better moisture retention.
No doubt the product is excellent but due to its perishable nature (no preservatives are used), the price tag for monthly treatments can become quite unappealing. Most of the ingredients in the product can be found in many average kitchens so making your own caramel treatment seems a more attractive approach for those who wish to use it on a regular basis.
By understanding the purpose of each ingredient, you can adjust the recipe every time you make it depending on your hair's needs.
Honey - An excellent humectant good for moisture
Olive Oil - For lubrication and helps with moisture retention
Bananas - Good for moisture and some protein benefits as well
Molasses (Treacle) - Another excellent humectant with some protein benefits
Water - This is the best natural moisturizer and is used to thin the mixture
Apple Cider Vinegar - For the shine it imparts to the hair
Cornstarch - For thickening purposes
Wheat germ oil - For added strength and lubrication
Here outlined is a simple recipe based on the ingredients above:
Honey - 6 tablespoons
Olive Oil - 6 tablespoons
Bananas - 2-3 overripe and very soft
Molasses (Treacle) - 3 tablespoons
Water - 4-6 tablespoons
Apple Cider Vinegar - 1 tablespoon
Cornstarch - 1-2 tablespoons depending on how thick you want the mixture to be
Wheat germ oil - 1 teaspoon - This can be substituted for any other natural oil of your choice
o Place all the ingredients except for the water into a blender and process until smooth. You may need to add the water bit by bit if it looks too dry.
o To ensure that there are no bits of banana in the mixture, sieve it through a fine sieve.
o Pour the mixture into a saucepan and put it on a medium heat while stirring constantly. You don't want to 'cook' the mixture but you want the cornstarch to cause it to thicken and this will take just moments. You may need to add more water to thin it down if it gets too thick or add a bit more cornstarch if it is still too runny. You want to end up with a caramel coloured mixture that is the consistency of a thick batter. If the mixture is too thin it will start dripping from your hair as soon as you apply it.
o Decant the mixture into a container, depending on the length of your hair it will likely be enough for two applications.
To apply, divide the hair into 3-4 sections and clip. Starting with 1 section, part the hair and apply on the roots generously rubbing in with your fingers. Once applied on the roots of the section, apply the mixture all the way to the ends. Complete all sections in this manner and once done, cover the hair with a plastic cap. Let the mixture sit in your hair for 1-2 hours or overnight for really dry hair.
Wash hair with a sulfate free shampoo, deep condition and style as usual. You can freeze the remainder until you are ready to use it. The treatment is suitable for both natural and relaxed hair.

3 Tips For What is the Best Face Cream For Women - For Youthful, Radiant Skin
Are you always looking for the best face cream for women, but can't find it? Don't worry, with these tips you'll soon have the right cream in your hands and get benefits like smoother, more radiant and younger-looking skin.
1. A Cream that Targets the 3 Causes of Skin Aging
The best face cream for women should certainly target the three main causes of skin aging, to put off the aging process and reduce lines and wrinkles. This is what should be addressed:
- A decreased growth of collagen and elastin which contributes to wrinkles, fine lines and unhealthy skin.
- A loss of hyaluronic acid, which causes sagging.
- Free radical damage which causes skin aging in general.
2. A Natural Product
By choosing a natural product you get closer to finding the best cream for face, because chemicals are generally a bad way to go.
In most regular skin creams you'll find risky chemicals like parabens, dioxanes and fragrances, all of which are suspected to increase the risk of cancer.
3. With the Right Amounts of Active Ingredients
Look for a cream with proven active ingredients like Cynergy TK which is proven to increase the growth of collagen and elastin, Phytessence Wakame which increases hyaluronic acid again, and Nano-Lipobelle H-EQ10 which counteracts free radicals.
But it isn't enough that they are in the face cream, they should be added in optimum amounts. There are many manufacturers out there who try to shortcut to profit by just adding a tiny amount of the best ingredients, just so they can write them on the label.
In the best face cream for women all ingredients are added in the same amounts as used in clinical trials with successful results, any lower and the cream won't be as effective as the trial.

Causes of a Sulfite Allergy Or Sulfite Sensitivity
A sulfite Allergy is when an individual has a sensitivity to sulfites which causes them to have an allergic reaction which could be mild to severe and in some cases life threatening. Sulfites are a common chemical compound which is sulfur based and can occur naturally in certain foods or are sometimes added to foods to preserve or enhance them.
Sulfites are also used in certain medications and an individual may not have a sulfite allergy early in life but then develop one later on which is a mystery to medical science as to what causes this condition to suddenly occur.
People who have been diagnosed with asthma are the most susceptible when it comes to having a reaction from sulfites. It is estimated that five percent of asthmatics will incur more severe symptoms of asthma when ingesting food which contains sulfites as well as if they come in contact with sulfite vapors or fumes.
Individuals with a low tolerance for sulfur-based compounds can have a severe and possibly life threatening allergic reaction called anaphylaxis when either consuming food or receiving any medications containing sulfur. Symptoms of an allergic reaction to sulfites can include nausea, vomiting, diarrhea, hives, and difficulty breathing.
A sulfite allergy diagnosis can only be definitively confirmed through testing which is performed under medical supervision by a professional who specializes in the field of allergies. This test is typically done by having the individual ingest sulfites in slowly increasing amounts while monitoring the patient's major organ functions and vital signs.
Manufacturers of food products are no longer allowed under the law to use sulfites on any produce which is consumed raw such as lettuce or fruits however, sulfites are in numerous processed foods but this can be determined by reading the label as manufacturers are required to list this ingredient on any food products which contain it.
