A Fresh Look at Lash Retention

So many lash techs will be baffled when a client comes back to then to say they have lost a lot more lashes than expected following lash extension treatment. Poor lash retention can occur for many reasons, we pinpoint the most common reasons in our blog this week to help take the guess work out of lash extension retention…


So many clients will be taking medications and it is easy to overlook the impact of these when filling out a client consultation. However, it can come back to haunt you when the client then fails to retain their lashes as you’d expect they should. Medications for conditions such as diabetes, digestive concerns like Crohn’s, circulation related issues, etc. can all affect blood flow to the skin and hair follicles resulting in lashes shedding more quickly than those without such conditions.

This then leads to poor lash retention as the natural lashes shed along with the extensions more quickly than usual. This is easy to work around with infill appointments at closer intervals, however, it must be discussed with the client to ensure they have a fair expectation of their lashes and the costs of increased maintenance.


Hormones hugely affect the hair growth cycle and also natural oils with the skin. Those in pregnancy or on hormonal contraceptives may find they have better than average lash retention, however, those breastfeeding or going through menopause may have reduced retention.

This is down to the benefits of oestrogen on boosting hair growth and retention, and then the shed many ladies see following the birth of a baby or when going through menopause where the hair can naturally thin. Hormones can also affect the balance of skin oils. Oiler skin may result in quicker lash shedding as it can contribute to breaking down of the lash bond prematurely.

Diet and nutrition

A diet rich in fats can result in oiler skin and greater lash shedding. Vitamin B is excellent for the health of the lashes, whereas a diet excessively high in vitamin A (as found in green vegetables and fish) may impair hair growth. Having an understanding of a well-balanced diet and its importance in the health of the lashes is essential to be able to guide your clients on realistic expectations for their lash retention and likely maintenance required.

Lifestyle factors

Those who swim regularly, use steam or saunas often, those who regularly work out; all are likely to shed their lashes more quickly simply from the effects of prolonged contact with moisture, heat, and sweat that can affect the lash bond. Discussing these factors with clients will help ensure they know how best to minimise damage to their lashes or indeed establish their suitability for lash extensions, over say a lash lift and tint treatment for example.

Understanding the reasons why some clients’ lashes shed more quickly than others will help you establish a suitable maintenance schedule and give a realistic likely cost of upkeep for new clients. Most techs come into difficulty when they fail to clearly communicate this to clients as it leads to disappointment or a feeling that perhaps the lash tech’s work was not up to scratch or that they somehow did something wrong. This may then lead the tech to lose a client or indeed damage their reputation. This is why it is so important to carry out a full, in-depth consultation allowing clients to freely disclose any conditions, medications and lifestyle factors.

It is also important, once you have a little knowledge, not to be tempted to give medical advice but to refer any clients disclosing conditions or medications with which you are not familiar, to their GP to check their suitability prior to offering lash treatments.
