Your body might be the culprit.

If you notice your hair changing colour, it could be due to an underlying medical condition. For example, Dr. Sari Hariri of New York City’s Wexler Dermatology Associates says that some women experience a change in their hair hue after giving birth and experiencing hormone fluctuations. “The body is producing less estrogen and more testosterone,” she says. “This can cause darker pigments or even blonde highlights to appear.”

It’s also possible that the culprit could be something like a medication or other health issue that you’re dealing with. If your doctor has prescribed you a new prescription drug, for example, it might take some time for your body to adjust—and when it does (often within six months), there may be some side effects including changes in skin tone and/or coloration of one’s hair as well as thinning hair or weight gain/loss (though these are relatively rare issues).

Lastly, if you’ve recently experienced an illness or injury—or have had surgery—your body chemistry will likely be thrown off balance temporarily until everything returns back to normal; this might result in temporary discoloration too!

You might have too much stress in your life.

You might be experiencing hair changes due to stress. Stress can cause your body to release a hormone called cortisol, which can affect the way your hair reacts to different chemicals. If you are feeling stressed, talk to someone about it or try meditation or yoga. Exercise is also a good way to relieve stress so that you don’t have any more problems with your hair colour!

You could be taking new medications.

There are a few medications that can cause your hair to change colour.

• Some medicines, like those used to treat high blood pressure, contain ingredients that make your hair fall out.
• Other drugs such as rosiglitazone (Avandia) and pioglitazone (Actos), both of which are used for diabetes, have been linked with gray or white hair growth.
• It is important to talk to your doctor about any concerns you have regarding this side effect before starting a new medication or continuing an existing one.

You could be eating too much sugar.

• Sugar is in many foods, including bread, pasta and cereals.
• Sugar is addictive and our bodies are craving it more than ever.
• Too much sugar can lead to weight gain, which can cause diabetes.

If you’re worried about your health or if you’re feeling bloated or tired all the time after eating sugar-rich food, speak to a dietitian who will help you cut back on sugar without feeling like your diet has become restrictive.

You might have a dietary deficiency.

• You might have a dietary deficiency.

Iron, vitamin B12, protein, essential fatty acids are the most common deficiencies in hair colouring. Iron is especially important for women, who lose more blood during menstruation than men do and therefore need to replenish their stores of this mineral in order to prevent anemia (a condition where your body doesn’t get enough oxygen). If you’re iron deficient and experiencing breakage or colour fade, consider adding iron-rich foods like spinach or red meat to your diet. Your doctor can also prescribe supplements in addition to your daily multivitamin pill if you need them!

You are not sleeping enough.

If you are not sleeping enough, it is likely that your hair colour will change. The exact reason for this is not fully understood by scientists but one theory suggests that a lack of sleep can cause problems with how the body metabolises chemicals in food.

As well as this, poor sleep hygiene can also be a factor: if you don’t get enough sleep and then go to bed later than usual the next day, it may result in an imbalance of chemicals in your body which can lead to skin damage.

If you want to keep your hair’s natural colour or maintain its health then make sure that you always have good sleep hygiene and get at least eight hours’ worth each night!
