Use a tiny dab of serum to smooth down any fly-aways or frizz. Concentrate on the ends of your hair, since they tend to dry out the fastest. Make sure you use the product sparingly – your hair can end up looking greasy if you use too much, which is not quite the look you’re going for! After applying the serum, wait a few minutes before moving on. This will give your hair time to cool down completely. Once your hair has cooled down, lightly mist a hairspray or finishing spray over your entire head to set the hairstyle. Another technique: spray the product onto the bristles of your flat paddle brush and then gently brush your hair with it. This can help to prevent any stickiness that the product could potentially cause. If you hear any sizzling when you spray on the product, this means your hair hasn’t cooled down sufficiently. The sizzle sound means you are causing damage to your hair, so set down your spray bottle and wait a couple of minutes for your hair to cool down some more. Your hair’s texture and length, as well as the climate where you live, will play a role in how your straight style holds up throughout the day. Think about using an anti-humidity (or anti-frizz) cream or spray if you live in a particularly humid area. Try styling cream if your hair is short and needs a little more weight to keep the curls from springing back up. The cream will lightly weigh the hair down and prevent this from occurring. Don’t be afraid to try something new; if it doesn’t work, you know you’re one step closer to finding a product that does! Experiment with a shine spray product, which will specifically add shine to your hair, but use it sparingly. These are often silicone-based products and will need a special shampoo to remove the residue. This process can definitely be time-consuming, so aim to do it every other day or every three days. Rock the always-fashionable shower cap in the shower to protect those silky straight strands from the water. In between washings, touch up your limp roots and remove oil with a dry shampoo.  Use a flat iron to spot-straighten any strands that have re-curled overnight. If you use smoothing and straightening tools and products on a regular basis, you run the risk of damaging your hair. Make sure to use deep conditioning treatments at least once per week to repair any damage and get your hair back to its usual gorgeous self. Happy straightening!

Before you mix diazinon, you should make sure it’s legal to use in your area. Diazinon is illegal for residential use in many places. Contact your local government or go online to see if diazinon is banned where you live. If you’re not sure, don’t use it or you could risk a high fine. Diazinon is highly toxic to wildlife and the environment if it isn’t disposed of properly. Diazinon is a highly toxic pesticide that can damage the nervous system of any animal or person that is exposed to it. Before you begin mixing your diazinon, you need to make sure that the area is clear of people and animals that could be exposed to it. Diazinon can also contaminate personal items like toys and tools, so remove them from the area as well. Diazinon can give off fumes that are noxious and dangerous in high concentrations. It’s important that you work in an area that’s well-ventilated to avoid exposure to the neurotoxin. If it’s possible, mix the diazinon outside.  If there is a breeze or a fan in the area you’re working, make sure the fumes aren’t being blown towards people. The toxic fumes can build up and remain in a room, so don’t mix diazinon indoors. Diazinon can also enter your body by getting on your skin and entering your bloodstream. Wear a thick long sleeve shirt, long pants, closed-toe shoes, and socks when you’re mixing diazinon to keep it from getting on your skin.  Button up your long sleeve shirt all the way to reduce the amount of exposed skin. Blue jeans are good long pants to wear to prevent exposure. Consider wearing a chemical-resistant apron to prevent getting any of the chemical on your clothes. Your hands are at the most risk of coming into contact with the diazinon while you mix it, so wear thick, chemical-resistant gloves to avoid getting any of the chemical on your skin. Make sure the gloves fit your hand and can be tucked into the sleeve of your shirt so all of your skin is covered. You can find chemical resistant gloves at most large chain stores. The neurotoxin in diazinon can cause blindness. Basic safety goggles will help prevent any of the chemical from entering your eyes. Diazinon is sprayed from a tank, so wear eye protection that also protects the sides of your eyes to prevent exposure from a splashback or deflection of the spray. Safety glasses or goggles can be purchased at large department stores and online. The spray mist of the diazinon is very easy to accidentally breathe in and the neurotoxin can cause serious damage to your nervous system. You need to use a full respirator to avoid the mist or the fumes that the chemical gives off. Make sure the respirator is fitted to your face well. In the event of a spill, you don’t want to use water to clean it up because it can just spread the diazinon around and could be harmful to the environment. Have paper towels and absorbent material like sawdust or kitty litter nearby to quickly soak up any spills. Keep garbage bags nearby as well to dispose of the cleanup materials.
