Using lukewarm water is best because it activates the cleansers in your shampoo while protecting your hair and scalp for your healthiest hair growth.
Cold water preserves natural oils and keeps your hair manageable, gives it a healthy shine and loads it up with extra moisture giving it a smoother and shinier look. Cold water helps close the cuticles. Closed cuticles are smoother cuticles which can give your hair some much needed shine.
Warm water should be used when cleansing your hair at the beginning of wash day. This is because warm water allows the cuticles of the hair and pores on the scalp to open up. This helps to deeply cleanse your hair and scalp to help remove any dirt, residue or buildup that is tightly packed in the cuticles and pores.
The main reason that distilled water is the best water for your hair is that it does not contain any minerals like magnesium or calcium like hard water does. Hard water leaves deposits on your faucets, glassware, and yes, even on your hair.

Using too much of hot water on the hair can lead to damaging effects. It is a myth that hot water rinse can help add softness to the hair. Rather, the fact is it can strip your hair of its essential oils and moisture that can leave your hairs all frizzy and dry to put it precisely.
The shower temperature should be between 104-110 degrees Fahrenheit (yes, that hot!). But it's with good cause: Warm water not only ramps up the cleaning power of certain cleansing surfactants, but it also helps to melt away styling waxes and the oils and sebum that can build up on your hair and scalp.
Washing the hair with hot water causes swelling of the hair shafts or frizzy hair. Warm the water and maintain a temperature just above the body temperature (100°F). This is ideal for washing hair and may prevent scalp irritation.
Heat causes frizzy hair, and hot water is no exception. No matter what your hair type, the hair needs moisture to stay frizz free. Because hot water can strip the hair of natural oils, moisture escapes the hair shaft and results in frizz.
Exposure to high heat changes the shape of your hair's keratin strands. Temperatures over 300°F convert the ⍺-keratin to β-keratin, which eventually leads to weaker hair that has lost its elasticity and become more prone to damage.
So, for every type of hair, it is suggested to remain below the 300-395 degrees threshold. Otherwise, you will burn away your beautiful strands. For thicker hair, the range of 300 to 375 is safe. While for thinner hair, remaining below 290 degrees Fahrenheit is ideal.

Hot showers and baths can inflame the skin, causing redness, itching, and even peeling — similar to a sunburn. They also can disrupt the skin's natural balance of moisture, robbing you of the natural oils, fats, and proteins that keep skin healthy.
It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging. Anyone can lose hair on their head, but it's more common in men. Baldness typically refers to excessive hair loss from your scalp. Hereditary hair loss with age is the most common cause of baldness.
Damaged hair becomes brittle and breaks easily. Your hair might look dull and dry, and the appearance of split ends is more noticeable. It can also be challenging to get your hair to lie flat.
Overuse of hot styling tools, such as your hairdryer, curling tong and straighteners, can make your hair dry, prone to breakage and consequently more likely to fall out, especially if you use them every day. This is because when too much strong, dry heat is applied to the hair it weakens the hair shaft.
When you're styling fine, processed hair with heat, 350°F/175°C is a safe bet. Anything over 370°F/190°C could potentially cause damage to your hair. HOT TIP: Prepare delicate or damaged hair with a top-notch heat protectant like the ghd Straight & Smooth Spray - Normal/Fine Hair.
